Re: FYI: Comcast Metro ethernet to the home
We had Fairpoint over here in Vermont for years and their service was pretty good, net and landline. Then last fall we asked to upgrade to their business account level in hopes of more speed. Within a couple of days we had no service at all, zero, and then ensued many weeks of email, snail mail and phone calls back and forth and getting nowhere. They also had the strike going on and apparently temps working the phone lines and going out to the field calls. Also reported sabotage of company equipment. Finally, we also reluctantly switched to Comcast (Saint Albans Bay) and it was better immediately, but in the past couple of weeks it's been dropping at random several times a day, no idea why. And our next-door neighbor asked me about then how our service was and I mentioned this; he said his has been the same and he was fed up. He was also shocked at how little we're paying and told me he started out paying that amount, roughly, but now, three years later, it's three times as much per month. So he's gone with the Dish network for tee-vee and net, I guess, and Fairpoint for landline. A local ISP outfit evidently has a tower on Hathaway Point, which is sort of opposite us across the bay here, but direct line of sight. I gotta ask him how it is when I see him around again. I keep hearing how the net is changing the universe and the cloud is wunnerful and so on but it looks like that's only for the big cities in Megalopolis. If we were trying to run a business that relied on the net here, which we are, it's not working out real well so far. Or take online courses and training. On Fri, Jul 17, 2015 at 4:37 PM, Steven C.

Recommendations for/against Comcast Business as an email provider
Slightly off-topic, although I got my foot stuck in this door since I have installed and maintain a LAMP server and apps at this client site. So, there's a bit of Linux in there. I have a client running a small business with my LAMP server as his only non-desktop machine, and Comcast Business for internet provider. He's been using a patchwork of email services over the years (they use AOL and Yahoo! email addresses and a former web design firm provides their domain's POP server.) They are entitled to Comcast Business email as part of their internet package. I wondered if folks here had experience with setting up other clients with Comcast. In particular, my concerns are reliability (losing email during business hours means lost business) and whether they provide decent spam filtering. I've set up other clients with Google and/or Google Apps Premier ($50/year/user) accounts, and their IMAP servers provide nearly 100% uptime and excellent spam filtering. Providing email, spam filtering and network support is really beyond the scope of my services - mostly software development and application support -- so I'm hoping to find a service reliable enough to just configure once and leave running, with the occasional rare tweak. I don't see these folks having any need for an inhouse mail server if reliable services are available elsewhere. I'd welcome any recommendations and/or experiences. -- Ted Roche Ted Roche Associates, LLC http://www.tedroche.com ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Re: Recommendations for/against Comcast Business as an email provider
In keeping with what appears to be list etiquette I have chosen to partially ignore your subject line and provide an alternative solution to your issue. :) I have not used email through my Comcast business connection (have Comcast + DSL for redundant connectivity at work). Instead I chose to use Postini (owned and run by Google) to filter spam, viruses, and provide uptime. They are NOT a free service but they are very cheap and VERY GOOD. It is simple to use and simple to setup. Via the Postini web interface I had to: add email addresses and aliases, setup my internal/receiving host server address, and specify some options like level of spam filtering, whether to accept or reject email to unlisted addresses, etc. After the intiial setup, adding an email address or deleting one takes about 1 minute via a web interface. To learn the interface, understand the options (it's google, it can take a bit), figure out all the actual addresses and aliases in use as opposed to just configured, and setup 25+ email addresses with an additional 40 aliases took about a day. Most of that was spent on items 2 and 3. My rambling point being: if you understand email options, it ain't rocket science to setup. At my internal site I had to setup postfix, web based email, and change my MX records to point to Postini. I also recommend you set the firewall to only allow external mail access from the Postini servers (after a delay to let the TTL for the old MX records die). Net result, EXCELLENT spam filtering and stats (over the last hour 95% of all my email never came down the pipe, currently all spam, no viruses), virus scans by multiple anti-virus, virtually 100% uptime (I've been down for maint before, they buffer several gigs of deliverable email) and ZERO complaints (OK, I too have a user or two that complains about EVERY spam message, that doesn't count). Cost is $12 per year per actual email address (not aliases, which are free). I think they have a more hosted version for about $25/year which MAY (or may not) be closer to what you want, I haven't used it. Pricing link for various service options/levels is: http://www.google.com/postini/compare.html They provide an email summary to each user about quarantined emails and the individual users can release their own quarantined messages if you like. They support user level white/black lists (again individual users can manage them via the web interface). I no longer have to update email anti-virus or spam lists, or deal with users white/black lists, or deal with spooling during down time, ... I get to keep internal email with internal email security, scripted backups, retention policies, etc. The is a very low/no maintenance way to get web based filtering and spooling but local email (no hacking of web email or social engineering of web passwords, local backups and retention). It gets you Google's uptime and spooling etc. that you mentioned, with some local control. Obviously the level of local control you may want/need is likely one of the deciding factors in your case. I think you can get a demo from them. If not, let me know and I'll be happy to show you the web interface if you are in the Nashua area.

It is just too tedious and time consuming to try to keep up with all of the latest and greatest steps necessary to hold off the spammers. So I setup my clients with Google Apps standard unless they specifically need the Google Apps Premier level of service. It saves me a lot of headaches and makes the clients happy too.

Boxee is an offshoot of XBMC and they share code back forth. One of the requirements of Boxee is OpenGL. I don't remember if XBMC requires it or not. I'm running Boxee on a Mac Mini as well as XBMC.

You keep expecting to find a way to capture content where it would make sense to have one. There isn't one, because the copyright cartels don't *want* you to have one. The digital channels are encrypted. They can only be decrypted by a CableCARD. The CableCARD checks the host equipment (set-top-box, TV with CableCARD slot, Tivo, whatever) for a crypto signature authorizing the host. CableLabs only hands out a signature after they're happy the host equipment will properly honor restrictions put in place by the copyright cartels. Those restrictions include enforcing copy restrictions on digital outputs. This is why your TV has to support HDCP (High Definition Copy^W Content Protection) in order to use an HDMI input to watch encrypted channels. The host will shut off the digital signal if it doesn't get the proper HDCP crypto. There is the analog hole, which is the copyright cartel term for analog outputs that can't be digitally copy protected. Available analog outputs are RF, composite (single RCA), S-video, and component. All but the last are fuzzy standard definition only, which was already available plaintext via RF, so the cartels didn't worry as much about them. Component allows for high def. Currently, analog-to-digital capture devices for high-def component video are expensive, so they have remained out of consumer hands. But the copyright cartels are still worried, and keep trying to get that hole plugged somehow, too.

Just to be pedantic, it's not *used* for Comcast Basic and Extended Basic. It's the cable operator who gets to decide. They're not using it for Extended Basic, so there's nothing to enforce. I don't know why Comcast doesn't encrypt their Extended Basic, but there you go. I'm honestly surprised the cable networks haven't mandated it. Comcast Basic means local broadcast channels, and the FCC says operators have to make those available for no additional charge, so I suspect it's actually cheaper for Comcast to send them plaintext. If they were encrypted, they'd prolly have to give out more equipment than they do now. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

There isn't one, because the copyright cartels don't *want* you to have one. The digital channels are encrypted. They can only be decrypted by a CableCARD. The CableCARD checks the host equipment (set-top-box, TV with CableCARD slot, Tivo, whatever) for a crypto signature authorizing the host. CableLabs only hands out a signature after they're happy the host equipment will properly honor restrictions put in place by the copyright cartels. Those restrictions include enforcing copy restrictions on digital outputs. This is why your TV has to support HDCP (High Definition Copy^W Content Protection) in order to use an HDMI input to watch encrypted channels. The host will shut off the digital signal if it doesn't get the proper HDCP crypto. There is the analog hole, which is the copyright cartel term for analog outputs that can't be digitally copy protected. Available analog outputs are RF, composite (single RCA), S-video, and component. All but the last are fuzzy standard definition only, which was already available plaintext via RF, so the cartels didn't worry as much about them. Component allows for high def. Currently, analog-to-digital capture devices for high-def component video are expensive, Where expensive is $200. Sure, not super cheap, but really not that much in the grand scheme of things. Of course, you also need a set top box to feed it. so they have remained out of consumer hands. But the copyright cartels are still worried, and keep trying to get that hole plugged somehow, too.

recording Comcast digital channels with MythTV
For several years, I've been running MythTV with a Hauppauge PVR-500 dual analog tuner.

As it happens, it was also mentioned in today's Boston Globe (page G2). There's a Linux driver: http://www.kernellabs.com/blog/?page_id=17 Unfortunately, it only handles digital so far. So I guess I'd need to keep the PVR-500 after all, and another splitter. However, I think this will only handle the clear QAM signals. How many channels does Comcast encrypt? For our regular TV (separate from the MythTV setup), we have a cable box (Motorola model DCT700/US) which I assume decrypts and converts from digital to analog. To record encrypted channels, I guess I could connect my current analog tuner downstream of the cable box. But I think that would only give me one channel at a time, and necessitates double conversion (digital-analog-digital-analog). What's a better solution? E.g. another kind of set-top box that just decrypts? More than one channel? Are there DRM issues with the HVR-2250?

Re: recording Comcast digital channels with MythTV
I believe the only digital solutions which currently support encrypted channels are: * Patch that does decryption of certain channels in violation of DMCA * Set-top box from cable company with FireWire interface. Some of these allow passing decrypted output to Myth, but some channels forbid this (and thus the hardware honors it.) --DT Van Zandt (Hi Jim!) On Sun, Nov 15, 2009 at 9:59 PM, James R.

No clue about today, but from what I understand, Comcast is moving towards encrypting everything they can, leaving only the things that are mandated to be unencrypted as such -- that would be the stuff that's also available over the air. For our regular TV (separate from the MythTV setup), we have a cable box (Motorola model DCT700/US) which I assume decrypts and converts from digital to analog. Correct. To record encrypted channels, I guess I could connect my current analog tuner downstream of the cable box. Yeah, you can do that. But I think that would only give me one channel at a time, and necessitates double conversion (digital-analog-digital-analog). Yep. What's a better solution? E.g. another kind of set-top box that just decrypts? More than one channel? Not aware of any such things. You can mix-n-match too though. I use a mixture myself -- cards similar to the 2250 recording clear QAM channels, a PVR-250 hooked to a digital to analog terminal thingy (basically, a very basic cable box), and an HD-PVR hooked to the component outputs of my HDTV cable box. First preference is to use the capture cards, second is the HD-PVR, then the PVR-250. Are there DRM issues with the HVR-2250? No. Can anyone point to a technical description of the Comcast channel lineup (analog, digital, HD, clear QAM, encrypted, ...) for the Nashua area?

Re: comcast routing problems
Every once in a while Comcast will change DNS servers. I generally set up my /etc/resolv.conf with my router as the primary: nameserver 192.168.0.1 nameserver 68.87.71.230 nameserver 68.87.73.242 This is assuming your system uses a static IP. I use a static IP since I like to ssh into it. If you are using a dynamic IP, let DHCp adjust your /etc/resolv.conf.

URL syntax (was: ComCast DNS hijacking)

That's what Gmail shows me, too, even with Show original. Gmail
can be a bit funky, but I think it's telling the truth in this case.
(cut'n'pasted right out of Firefox's address bar)
Be aware that for some browsers (including Firefox), what you see in
the address bar may not be the URL as the protocol processes it.
Firefox will show you the decoded result (complete with characters not
allowed), but send the encoded version, and if you copy to clipboard,
you get the encoded version. This is generally what you want, but it
occasionally leads to confusion. Since you clipboarded it anyway,
this shouldn't be one of those times.
... no MIME encoding or anything like that was involved.
FWIW, the %00 notation is not something MIME knows about. AFAIK, it
was invented for WWW, and is just called URL encoding.
Is it bad form to use literal ampersands in emailed URLs?
I wanted to say that ampersands are reserved in URLs, but I just
checked, and official sources seem to say they are allowed.
The original Mar 1994 URL specification calls ampersand safe, and
does not place it in the reserved character list.
http://www.w3.org/Addressing/URL/url-spec.txt
RFC-1738 (Dec 1994) says ampersand *may* be reserved in some
schemes, but specifically allows it in HTTP host paths.
http://tools.ietf.org/html/rfc1738
RFC-3986 (Jan 2005) says host paths consists of segments, and
segments consist of pchar's, and pchar's include sub-delimiters, and
an ampersand is a sub-delimiter. It also states that the semantics of
query parameters are outside of the scope of the URI spec, beyond the
use of question-mark (?) to separate the query from the path. It even
specifically mentions that the equals sign, as with field=value, is
not part of that spec. http://tools.ietf.org/html/rfc3986
The ampersand/equals syntax used in HTML forms submitted via GET
appear to be defined by the HTML specification, as
application/x-www-form-urlencoded. It's not mentioned anywhere else
that I can find.
http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4
So all that suggests that an ampersand is perfectly legal in a URL.
So I guess the failure is in software at Dan's end.
It may be worth noting that ampersand is reserved in
{SG,HT,X,XHT}ML, so you can't put a URL containing an ampersand in an
HTML document literally; you have to encode the ampersand as an *ML
character entity (amp;).
In general, I suggest avoiding everything but letters, numbers,
dashes, periods, and underscores in URL path components, for just this
sort of reason.

See http://scte65scan.sourceforge.net/ From the website: Scans for in-band SCTE 65 tables. Allows automatic mapping of virtual channel numbers to callsigns and physical channels. Useful for the transition from analog CATV to digital CATV. Comcast is one such cable provider making these tables available. p.s. You'll see the acronym 'POD'.

If I recall correctly, the digital version of a standard-def program actually consumes less bandwidth to transmit than the analog variant of the same, so they can cram more digital channels into a multiplexed QAM channel than they can analog channels. On top of that, they can encrypt the digital channels, making it harder for 3rd-party tuners to be useful (be they tuners in a mythtv box or the built-in tuner in an HDTV), thereby requiring subscribers to rent more cable boxes...

The DTA converters are given to subscribers on request (up to two per household). Additional ones are charged. Like Ben said, I think you can also get a cablecard for no fee. The DTA thingies bother me because it's one more thing you have to plug in, that is always on, and you need another remote, that uses another battery, and another receiver to place on top of your set/furniture. Free in this case means we pay for it in our service fees (there is a lot of cost and overhead to implement this), and we obviously pay for it in the above ways. btw, at least in Newburyport, Comcast has been advertising this heavily with automated calls, mailings, newspaper ads.

In message 51ab7d3a-d3ee-49db-b44f-70bca4f1b...@wilsonet.com, Jarod Wilson wr ites: thereby requiring subscribers to rent more cable boxes... You got it. Selling less and charging more for it has been this company's mantra since... well, when did they become Comcast? Last June (almost 1 year ago), I lost three channels (4, 40, and 58 if I recall correctly) because they moved them to the digital tier. I, personally, find it disgusting how Comcast is using the *OTA* DTV transition as an opportunity to rob analog *cable* TV subscribers of service in the name of digital programming. Most people don't understand that digital cable has nothing at all to do with what's digital on the air. As a result, the uninformed perception is that what Comcast's doing is government-mandated. It's patent deception. To drive the point home... the DTV transition began in February, and Comcast is *still* broadcasting commercials (on analog cable, mind you) urging people to be ready for the end of the transition in June. Let me ask you this: if you're watching that commercial on analog cable, don't you already have at least basic cable??! Clearly, the intent here is to mislead the uninformed. Comcast gets to cram more signal into less bandwidth... saving them money. At the same time, if I want the Hallmark Channel back (that was channel 58, I think), I have to rent one of their cable boxes. And, don't forget... Comcast's new TOS declare that their cable boxes, as well as ALL software and settings on them, are Comcast property. That means they can change settings, upgrade software, etc. on your box without your knowledge. (Someone on this list recently complained about surprise changes made to a cable modem.) IIRC, the TOS even grant Comcast explicit permission to come into your home and physically change out cards in their CPE. (No joke!) Because the digital boxes have channels back to Comcast, and they can change set-top software at will, it's possible for Comcast to track subscriber viewing habits. Warrantless set-top surveillance, anyone? No, I'm afraid I'll have to pass. I'm plenty ready with my analog tuner card, thank you! ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

The scenario here (for me, and I believe the OP) is rewriting email
addresses, not masquerading as a different host.
Two have people suggested a config directive for Postfix:
myhostname = foo.example.com
Now, I don't know Postfix, but I'm guessing that sets the hostname.
:) Since confusion over hostname and reverse-path was seen earlier,
and is being seen here, I am going to spell things out step-by-step,
in the hope of establishing mutual understanding. :)
I've got:
myorigin = venix.com
The commented section of main.cf:
# SENDING MAIL
#
# The myorigin parameter specifies the domain that locally-posted
# mail appears to come from. The default is to append $myhostname,
# which is fine for small sites. If you run a domain with multiple
# machines, you should (1) change this to $mydomain and (2) set up
# a domain-wide alias database that aliases each user to
# u...@that.users.mailhost.
#
# For the sake of consistency between sender and recipient addresses,
# myorigin also specifies the default domain name that is appended
# to recipient addresses that have no @domain part.
#
#myorigin = $myhostname
#myorigin = $mydomain
myorigin = venix.com
Obviously you will want a different domain than venix.com.
(snipped)
Example: My PC's hostname is blackfire. I've got an /etc/hosts
entry that will cause that to canonicalizize to
blackfire.local.bscott. So when my MTA (Sendmail) talks to Comcast,
it HELO's as blackfire.local.bscott.
My user account is bscott. By default, my MTA would build my
email address as bsc...@blackfire.local.bscott. That's obviously
invalid outside my LAN.
My public email address right now is dragonh...@gmail.com.
Changing my MTA's idea of my hostname to gmail.com would yield
bsc...@gmail.com, which doesn't help.
I could rename my account. But then if I wanted to switch to my
Comcast address (which is bscott...@comcast.net), I'd have to change
everything again. If I get my vanity domain working again, I'd have
to rename my local account to public, so my default email address
would be pub...@dragonhawk.org. My account name is used in config
files all over my PCs; this would be a mess.
So, what I want to do is tell my MTA to rewrite bscott and some
variants to dragonh...@gmail.com. My MTA can keep on using
blackfire.local.bscott for its hostname, but I want it to modify the
reverse-path.
Do do that, I add an entry to the Sendmail /etc/mail/genericstable,
which looks like this:
bscott dragonh...@gmail.com
For a hypothetical other user on my PC, I could add:
bobama presid...@whitehouse.gov
Using myorigin is too simplistic for your example. It would simply
rewrite bscott to bsc...@venix.com
The scenario here (for me, and the OP) is rewriting email addresses,
not masquerading as a different host. :)
So, {can, how would} this be done in Postfix and/or Exim?

OK, at work now, so I can check my server... here's what I've got (as an
example):
virtual_alias_maps = ... regexp:/etc/postfix/virtual-regexp
recipient_delimiter = +
and in /etc/postfix/virtual-regexp:
...
/(.*)\-(.*)@bfccomputing.com/ ${1}+$...@bfccomputing.com
This example rewrites (using 'example' in place of 'bfccomputing' for
spam harvesting reasons) bill-gnh...@example.com to
bill+gnh...@example.com. The recipient_delimiter allows
bill+gnh...@example.com to be delivered to b...@example.com, though
that's extraneous to the original example. Most web forms fail to
properly encode their input, and they assume + means %20 due to
historical insanity.
So, given a working knowledge of PCRE, the above should work fine in
most scenarios. I think it works in both directions, as I've got:
#/(.*)\-(.*)@(.*)/ ${1}+$...@${3}
commented out due to hosing outbound mail.
Remember to postmap(1) your regex file.

P.S. Has anybody thought of setting up spam traps with bait addresses
that would evaluate to destructive system calls?

For traditional Unix systems, the MUA is not responsible for building the email address. That's the job of the MTA (or the MSA if the system has that concept). sendmail(1), in other words. (I'm talking about sendmail the command here, not Sendmail the implementation.) As far as proper configuration of *that* goes, I think that lying about one's hostname is not proper. :) My hostname is not comcast.net, nor does my IP match that domain name. None of my account user names are valid email addresses at Comcast. Most of my email addresses are not there, either. If you really want your MTA's hostname to be proper, you need to find or create a domain name that matches your IP address, and set your MTA to use that. And if you have a dynamic IP address, you'll have to keep updating one or both. That's certainly doable, but I don't think it's worth worrying about. As detailed previously, the MTA's hostname really doesn't matter all that much in this scenario. The vast majority of Windows MUAs don't submit with a valid HELO, so any ISP relay filtering on that is going to block a lot of mail (and thus most likely go out of business). And a nominal MTA operated for purposes of Mail Submission is not the same thing as being a Mail Exchanger. MX'es should have proper hostnames, so problems where mail routing matters can be traced. I understand your edge case about gmail but I think you can consider yourself fortunately unique in that scenario. How so? This is a semi-regular issue on this and other mailing lists, so apparently people running *nix mailhosts run into the problem a lot.It certainly applies to the post which kicked off this discussion. :) I suppose many people these days just use a GUI MUA which talks direct to an ISP SMTP MTA/MSA/relay server, of course. But that leaves your base OS unable to send or receive email. How quaint. ;-) On the broader topic of getting mail through, though, you need to use real hostnames when speaking SMTP on the Internet. I find that statement misleading at best. A bogus reverse-path tends to cause much bigger problems than a bogus hostname. In practical use, you need to have a proper reverse-path, including a valid domain, for mail to work. Without it, DSNs (bounces, receipts) won't make it back to you. Some types of mail replies may not work properly, either. And most important, the majority of active MXes reject mail if the reverse-path domain does not resolve. MTAs operating for Mail Exchange *should* have a proper hostname. It's very useful for diagnostic purposes. Received headers are often used for heuristic spam analysis. But having a bogus hostname, especially if all you're doing is relaying through an ISP, is a mostly minor problem in practice. Comcast can't reject all mail with a From: other than comcast.net or doing round-trip DNS lookups as they'd break 77.6% of their SOHO users' e-mail. Of course. I never meant to suggest otherwise, and indeed, the fact that you bring it up makes me think I'm still not explaining things well. I'm not saying that mail originated on Comcast's network should have a reverse-path with a comcast.net domain part. I'm simply saying it should have a reverse-path which actually leads back to that mailbox (or a related one). That certainly appears to be the case for the original post in this discussion. Reverse-path was set to m...@e521, when it should have been michael.odonn...@comcast.net. Simply changing the MTA hostname to comcast.net would have changed the reverse-path to m...@comcast.net. That might have made the submission go through, but DSNs would still be mis-routed. Aside: In discussions like this, it is important to keep clear the distinction between envelope (RFC-821, SMTP) and message (RFC-822) addresses. So when referring to the RFC-821 stuff, it's best to write MAIL FROM or reverse-path, since From: is conventionally the RFC-822 header. (RFC-822 headers are completely irrelevant to SMTP.) I'll sometimes also reject mail with bogus Received: headers so using a valid hostname is important there too. One can certainly do this, but it will block a lot of mail from Windows MUAs. I suppose some might consider that a feature. ;-) It will also block mail that originates from inside private corporate networks. I routinely see private hops in the Received: headers. Heck, that's how we do things at $DAYJOB. I don't like stripping such information, either. It is often very useful diagnostically, even if I can't touch the MTAs directly. (Some advocate stripping the information to hide details of one's internal mail systems, but I don't see a real security benefit there.)

How does one do this in Postfix and/or Exim? From the Webmin help for Canonical Mapping (install webminhttp://webmin.com/to make it easy): The optional canonical file specifies an address mapping for local and non-local addresses. The mapping is used by the cleanup(8) daemon. The address mapping is recursive. The file serves as input to the postmap(1) command. The result, an indexed file in dbm or db format, is used for fast searching by the mail system. The canonical mapping affects both message header addresses (i.e. addresses that appear inside messages) and message envelope addresses (for example, the addresses that are used in SMTP protocol commands). Think Sendmail rule set S3, if you like. Typically, one would use the canonical table to replace login names by Firstname.Lastname, or to clean up addresses produced by legacy mail systems. The canonical mapping is not to be confused with virtual domain support. Use the virtual domain https://mail.datdec.com:3748/help.cgi/postfix/virtualmap for that purpose. The canonical mapping is not to be confused with local aliasing. Use the mail aliases https://mail.datdec.com:3748/help.cgi/postfix/aliases map for that purpose. The format of the canonical mappings is as follows, mappings being tried in the order as listed: - *u...@domain* mapped to... *address*: u...@domain is replaced by address This form has the highest precedence. This form useful to clean up addresses produced by legacy mail systems. It can also be used to produce Firstname.Lastname style addresses, but see below for a simpler solution. - *user* mapped to...*address*: u...@site is replaced by address when site is equal to $myorigin, when site is listed in $mydestination, or when it is listed in $inet_interfaces. This form is useful for replacing login names by Firstname.Lastname. - *...@domain* mapped to...*address*: Every address in domain is replaced by address. This form has the lowest precedence. In all the above forms, when address has the form @otherdomain, the result is the same user in otherdomain. ADDRESS EXTENSION: When table lookup fails, and the address localpart contains the optional recipient delimiter (e.g., user+...@domain), the search is repeated for the unextended address (e.g. u...@domain), and the unmatched extension is propagated to the result of table lookup. The matching order is: user+...@domain, u...@domain, user+foo, user, and @domain .

Re: Postfix/Exim sender address rewriting (was: Postfix ... ComCast port 587)
At least one person is confused here (me); possibly everybody. :-)
The scenario here (for me, and I believe the OP) is rewriting email
addresses, not masquerading as a different host.
Two have people suggested a config directive for Postfix:
myhostname = foo.example.com
Now, I don't know Postfix, but I'm guessing that sets the hostname.
:) Since confusion over hostname and reverse-path was seen earlier,
and is being seen here, I am going to spell things out step-by-step,
in the hope of establishing mutual understanding. :)
The sender's email address is given in the MAIL FROM verb when
handing off mail to another MTA or MSA. This is also called the
reverse-path. The reverse-path is used to route DSNs (bounce
messages and return receipts). Other than as described below, the
MTA's hostname has nothing to do with the reverse-path.
The hostname is what an MTA identifies itself as. That will get
used in HELO (or EHLO). The HELO name normally has no bearing on mail
routing; it's just a protocol feature for diagnostic convenience.
In particular, in the original poster's scenario, and to the best of
my knowledge, Comcast's relay servers do not appear to care about the
HELO name.
However, Comcast *will* reject on a reverse-path which specifies a
domain which does not resolve to something which can receive mail.
This makes sense; if the reverse-path is invalid, the sender cannot be
contacted, so they have no business sending email.
In particular, using c-99-999-999-999.hsd1.nh.comcast.net as the
domain part of the reverse-path isn't a particularly good idea, unless
one has a static IP address.
Now, the hostname does have one connection to the reverse-path: It
is usually used to build the revere-path when an MUA submits a message
to the MSA or MTA. A bare Unix username like bscott is not an email
address. By default, most MTAs canonicalizize the Unix hostname into
a FQDN, and then append that to the username to get an email address.
Example: My PC's hostname is blackfire. I've got an /etc/hosts
entry that will cause that to canonicalizize to
blackfire.local.bscott. So when my MTA (Sendmail) talks to Comcast,
it HELO's as blackfire.local.bscott.
My user account is bscott. By default, my MTA would build my
email address as bsc...@blackfire.local.bscott. That's obviously
invalid outside my LAN.
My public email address right now is dragonh...@gmail.com.
Changing my MTA's idea of my hostname to gmail.com would yield
bsc...@gmail.com, which doesn't help.
I could rename my account. But then if I wanted to switch to my
Comcast address (which is bscott...@comcast.net), I'd have to change
everything again. If I get my vanity domain working again, I'd have
to rename my local account to public, so my default email address
would be pub...@dragonhawk.org. My account name is used in config
files all over my PCs; this would be a mess.
So, what I want to do is tell my MTA to rewrite bscott and some
variants to dragonh...@gmail.com. My MTA can keep on using
blackfire.local.bscott for its hostname, but I want it to modify the
reverse-path.
Do do that, I add an entry to the Sendmail /etc/mail/genericstable,

For a hypothetical other user on my PC, I could add:
bobama presid...@whitehouse.gov

Yup, that did it - I'm transmitting this message from the
machine in question rather than that icky WWW tool - many
thanks. That error message about the Certificate on the line
just before it was apparently just intended to confuse me.
The setup scripts for the various MTAa have always used the
machine's hostname which, of course, is only known on my
little internal network and is not the hostname assigned to
my modem's WAN connection and from which the client appears
to be connecting. In the past the ComCast SMTP server didn't
care how my clients ID's themselves but that's apparently
tightened up when using this submission protocol.
Dang. This means it's going to be a PITA to keep my Postfix
config files up to date such that they stay in sync with that
externally visible hostname since it changes every time I get
renumbered. I'll guess I'll have to do something scripty to
rewrite the config file and then restart Postfix every time
it happens. -/

My guess: Many (most?) MTAs which are doing TLS are using self-signed certificates. So you'll get SMTP TLS trust errors by default in many MTAs.

This means it's going to be a PITA to keep my Postfix config files up to date such that they stay in sync with that externally visible hostname ... I'm no expert on Postfix, but from the logs, it appears Comcast is rejecting your SMTP reverse-path (MAIL FROM), not your hostname (HELO). (Windows mail clients almost never provide a valid HELO, so I would be amazed if Comcast would require that.) Configure your MTA to rewrite the reverse-path to be a valid address -- your email address would be appropriate. For example, with Sendmail, I just put the following in my /etc/mail/genericstable: bscott dragonh...@gmail.com I presume Postfix has a similar capability. Exim may as well. Anyone? You *really* should have a valid SMTP reverse-path anyway. Without it, most hosts will reject your mail, and you also won't be able to get non-immediate DSNs (Delivery Status Notifications). In the past the ComCast SMTP server didn't care how my clients ID's themselves but that's apparently tightened up when using this submission protocol. I'm kind of surprised. Validating MAIL FROM has been a best practice, and a very common practice, for longer than a decade. I don't think Comcast has ever let me relay mail through their systems with a bogus SMTP reverse-path. Are you sure this isn't something that changed when you changed MTAs? -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

They actually do document this, but it's all couched in terms of Windows mail client configuration, so you prolly ignored it. And the fun part about unauthenticated SMTP is that they have no easy way of identifying the legitimate users still using the old school methods. (Comcast gave up on tracking CPE MAC addresses a long time ago, so they have no way of telling you apart from the many other people on your optical node.) Scraping the email addresses out of the mail traffic is not feasible because of spam. From the discussion here on this list when I whined about about it, it seems that Port 25 is the default for Windows spamming machines Umm... spammers, like mail operators, have found that sending mail to ports other than port 25 highly reduces the delivery rate of mail. This applies to Unix hosts, too. :-) It is true that most spam comes from compromised Windows boxes, though. Comcast, like many ISPs these days, is not allowing consumer computers to send direct to MX because the overwhelmingly vast majority of such mail is spam. They're requiring sender authentication to help track spam that gets relayed through their mail exchangers. They're using port 587 because that's the RFC specified port for mail submission. Comcast be in the process of deploying TCP/25 blocking throughout their entire consumer network, to help stop spam sooner. This is actually a good idea. There's a few different reasons why they might want to reject mail submission via TCP/25, including performance gains through blocking blind spm, attack surface reduction, pig-headed standards compliance, andeasier diagnostics, but the big one would be it would mean they wouldn't have to worry about making TCP/25 exceptions for their relay servers throughout their network. This might actually be a good idea in the long run, but it hurts now. -- Ben ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

Postfix authentication to ComCast port 587
[ this msg transmitted via ComCast's godawful WWW email tool ]
Once upon a time, ComCast invited customers to send copies of SPAM
messages (those few which managed to get past ComCast's filters)
to a particular email address, so I rigged my system to do so
because I presumed they'd use them to better train their Bayesian
recognizers, or some such. I must say, I was happy to cooperate
because their filters seemed quite effective and very little
SPAM got through. But, of course, no good deed goes unpunished;
ComCast has consequently just summarily decided that *I* am a
SPAM source and blocked all outbound traffic on port 25 (SMTP)
and decreed that I may only use port 587 (submission) which my
configured-and-working-for-at-least-10-years Exim installation
seemed incapable of coping with.
So I replaced Exim with Postfix in an attempt to get back on
the air and made considerable progress. I *think* I'm to the
point where if I can figure out WTF is going on with Certificates
and such I might be in good shape. Details shown below (errors
toward the end); any help or advice gratefully accepted, though
please be informed that I am addicted to my local MH setup and
very much want to get this working, so recommendations like
just give up and use Gmail aren't really what I'm after... -/

You should at least get a bounce message from your own server since it
