[Mitch says:] Hey Gord - I realize what a hardlink is - but when you use virtual users, they are often using only one real unix id, so that's not an issue there... and from what I understand about maildir, the file is never modified - a client which "edits" a message, deletes the original and creates a new one - right? > It's really not worth being concerned over until you have as many users > as google, and a lot of duplicate messages sent to the bulk of them.

[courier-users] Question about storage architecture? Hardlinks for multiple deliveries?
I did some googling – I thought this idea had come up before can’t see it though – we were reviewing the number of messages on our system with multiple recipients and came up with more than a few – my understanding is that Gmail uses a hardlink-like system to basically reference count messages received – saves on storage demands and makes their marketing needs easier… Could something similar be accomplished with courier (not the marketing – just the storage savings!) I’m not expecting an instant change – now or ever – just throwing out the idea to consider the relative merits and difficulties… In our case we have condense our maildrop processing into maildroprc – users don’t run custom scripts – conceivably a single message could be delivered to ALL recipients instead of a copy for each. This would reduce processing and storage demands drastically – I see a lot of difficulties to be overcome just curious what people think. Thanks! m/
[courier-users] Debugging an error 534
I’m getting error 534 on my courier server when ONE remote client connects and tries to send mail… they claim they are sending to a single recipient – I obtained a copy of a message received on another non-courier server, and looked at the headers – I don’t see anything. Is there a way to capture the message and determine where the problem is? I know it’s their problem, but it would be good if I could help determine the source… I could turn on bigbrother, or maybe use some tcp packet capture?

I'm wondering how much work it would take to add the ability to optionally encrypt the Courier mail spool. [Mitch says:] I would think it'd be pretty major - you'd have to look up keys - do all the work - a number of API's would have to have params or information storage for the keys added, etc. Can I ask what the thinking behind this is? If you can't trust root, nothing is safe - root could always read the keys from a memory dump etc. If you can trust root, directory security should keep people safe... if you worry about media theft, consider an encrypted file system? If you don't trust the platform at all, then maybe you are trying to fix the wrong thing? Write a new mapi provider (or other) that resides on the client and does the work - or use PGP... at least this defers the encryption overhead to the client side... Iirc, at least one version of the web client Sam wrote allowed for GPG - which could be done on windows as well...

OK, this hack could be slighly complicated to add blank line only if a
message doesn't have any body lines.

[Mitch says:] I understand Sam's concern about modifying all messages and
thing he's right, but there has to be something easier than replacing the
broken clients and less brutal than what I do now (discard all messages too
small to be useful ;-)
Some people get a lot of these messages - and although I've tried to
convince them to fix their own problem by logging into webmail they persist
in the notion that it's a server problem - I don't know if these messages
didn't exist when they were at former hosts, or if the bug in the client
didn't exist at that point... or if sendmail, exim or other somehow patch
their messages...
In short - if Sam would accept a better patch then I'd sure appreciate if it
was there ;-)

You might be the only one who knows enough about the internals for these... If I do the above, my problem would probably be a fiar bit of inefficiency - the servers have many IP addresses, and if I have to list them all in the generic config instead of a listen_all, that results in a file handle per connection and some overhead in other areas right? That wouldn't be the best - if I have to do this, I guess I could use a different port, and configure webmails to you that port though - that way I can keep both daemons on listen_all, and avoid the difficulties that would otherwise result from IP adding and deleting. BUT... Is the limit in effect for localhost? (Just checking if that's a special case... I found an OLD note I made that at one point I thought it was - not sure if I was right then or if it still applies though...) Is there an error message generated when this condition occurs - something I could find in the logs? At this point I can't even be sure that's my problem. I only get told about the problem about once a week - used to be once a month though... Same question I guess applies to other limit conditions... like MAXDAEMONS, MAXPERIP etc. Is there a way to detect if the limits are being tested? I don't want to set them unrealistically high, but I also don't want a limit of 40 instead of 50 or whatever to cause 1 or 2 client complaints a day ;-) Thanks again. m/ --- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?

[courier-users] imap / pop3 maxperip - how to detect a problem and override on a per-ip basis?
Hi - think I MIGHT be having troubles with connections to my imap and pop3 daemons... think they MIGHT be due to limits in the MAXPERIP, but they are intermittant, and before I raise limits and open myself up to a dos attack I thought I'd ask if there is a way to verify? Does anything specific show up in the logs if the limit is reached? Is there a way to override the limit for known "good" hosts? We have some webmail clients on local servers - so I'm wondering if I can set a special limit for them, or if I have to run different processes... like one on a separate address, and firewall or screen it from public view and use it only for the "good" clients? The symptom I'm seeing is errors connecting to the server by the webmail client - don't know if they webclients are at fault (users can't be trusted to report the error reliably, and it isn't an apache error per say, so there's no log of it... Also - I know I've seen it before, but every time I look I can't find it - is there a central doc of all the bofh options? When I look on the courier site I don't see one, but I'm sure I have before...

Currently I've got a rather nasty little wrapper around maildrop to allow it to pull in additional fields from my user tables... I had visions... 1) that the new auth library and all things that call it could pass as output, but otherwise ignore additional fields from the user query 2) that maildrop could pull in this information so that I could avoid the wrapper... This would be an easier and more efficient hack if the programs which use the auth library could somehow just ignore additional fields returned... that way if I managed to hack the auth library and maildrop, I at least wouldn't have to revisit everywhere that calls the auth library? Of course maybe with the new system I'm missing a new and better way to do what I want... My goal is simple (in idea, but not implementation ;-)... To control all user accounts through a central maildrop script relying on database stored options... with my wrapper I've done this already, and works to allow things like activation of various maildrop actions, filters, xfilters etc. and even auto responses...

Someone said at one point that it would be too much work or put too much load on the db server... I don't understand how it would be more work than just storing the accounts as I do now, EXCEPT that at present, courier itself doesn't have ANY access to the database... All the access to db is done through the authentication module, which has limits on the number of active db connections and so on, so it won't overload your db when you get hundreds of connections to the smtp server. If you patch courier so it does something like this, you have to be aware of the load, and possibly have to create your own alias daemon to support this... I'd had to write a wrapper for maildrop so I could get all my db stored information into the context of the maildrop program for processing - ideally I should do the same one day... I needed full details on my user records (from db) to determine how to apply various filters, cc's, etc. If you were doing it "right" it might be something Sam would get behind and incorporate as an option... ask him?

Create a filter. If you are delivering through maildrop, you can put your filter in maildroprc, and have it effect all messages.

For me, it wasn't a problem if outlook was reading imap, but when reading pop, if it gets stuck on a message, that message remains in the queue for next time. Our first recommendation to effected users was to switch to imap or set up imap as a secondary way to clear the bad message. We had some people use their webmail login for this purpose.

[courier-users] odd pop3 password bug in courier-0.44.2
Ok. Before you flame, there are a bunch of ways you could blame this on me or Microsoft. That's besides the point ;-) Here's what I did: 1) set up mail account in outlook 2) copied users password from spreadsheet 3) pressed "send-receive" Got no mail. The logs indicate a successful pop login and out, with no errors, and mail messages sitting in "new" are moved to "cur" but NOT DOWNLOADED. What I found after much head scratching, is that the spreadsheet appends a newline I think ( or carriage return?) (try it yourself with excel) to the cell you copy and paste... Outlook isn't smart enough to trim the password field. On the other hand, there is no error from courier. So is it a courier problem in that it doesn't log the error? Or is it the extra newline that's throwing outlook off? I have my fix - don't want to be beaten up for my error, just think that if it is causing the pop3 session to crap out and yet isn't logged, then we should have an error message in courier for that. cheers. m/ --- This SF.Net email is sponsored by: YOU BE THE JUDGE.

RE: [courier-users] Planned changes to Courier's authentication library.
> I'm planning to make the following structural changes. This is the only > chance for someone to talk me out of it. > Not wanting to miss my chance ;-) Not sure if this is the appropriate time to consider a few issues or not - and maybe they have been addressed elsewhere while I wasn't looking - if so, forgive me. I handle these parameters in my user database, and assume if that's where they are, they might be retrieved through the auth lib... 1) As one other responder mentioned, use of authentication fields within maildrop is often useful. Although we can write custom queries, we can't pass any additional fields into courier for maildrop or filters to consider during the run. e.g. does a user want a global filter enforced, or does a user want spam moved to a subfolder. Currently I address this with a maildrop wrapper, which makes a second query to the user database, fetching all the extra config values and storing them in the environment, then calls the original maildrop. Not efficient, but it works. 2) As someone with a lot of domains (by my standards anyways) I have been trying to segregate users mail to their appropriate IP's. That means [EMAIL PROTECTED] should not be accepted through domain2.com's ip, and ideally, should not be sent through the default system ip, but rather the ip appropriate for that domain name. Currently no way of working around that, the result being that a few high volume users have tried (sucessfully) to put their usage on another users bill by using their ip. This is just an extension of the code existing that serves to restrict operational services - yes? 3) SSL services per IP - connection to auth here is more tenuous, just that the user-ip link is in my auth tables. I've mentioned these things before, and realize they may not be mainstream, or easy, but thought that as this was the "only chance" it was worth mentioning in case others have the same needs. Thanks again for the awesome tool. m/ --- This SF.Net email is sponsored by: YOU BE THE JUDGE.

RE: [courier-users] DEFAULTDELIVERY
The message is pretty self explanatory. Cannot have world/group permissions on the filter file - for your own good. Very simply, this means your .mailfiter file has to be more 600 - not 644, 666 (which is inherantly evil anyways - right?) Kidding asside this is about user permissions - courier is refusing to process a filter file which has write (or any? can't remember) permissions assigned to the group or world...

[courier-users] How to send from a non-replyable address?
I have a support system tool which we do not want to accept reply emails to... for a variety of reasons, I want to configure it to send notifications that will not be repliable to...

[courier-users] mailbot for virtual users? Read message from MySQL?
I'd like to start using mailbot, but I've got a bit of a problem... I maintain my vacation messages in a MySQL database along with the login info etc. One solution I see would be to have mailbot load the message from the database, but I am not a C programmer... I have hacked things occasionally but wouldn't call my self a C guru ;-) One alternative I see, is to forge dumping the message from MySQL to a temp file every time a vacation message is to be sent, but that seems wasteful. Another possibility I guess, would be to get mailbot to accept the message on another input stream and open that socket in the calling program and push the data in that way, but again that requires C skills ;-) Any thoughts on if this might happen in some form? Or am I better off to do the temp file idea. Thanks. m/ --- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!

RE: [courier-users] Email Autoresponder?
I personally have not done this, but I read this recently:
http://www.courier-mta.org/mailbot.html
Which seems to show a better way to do things ;-)
This is from my maildroprc:
## LOOK INTO MAILBOT FOR RESPONSE LIMITING ETC!
BADLOOP="mail_loop_detected"
if ($UI_EnableVacationMessage eq "Y" && ! /^FROM_DAEMON/ && ! /^X-Loop:
$BADLOOP/)
{
/^Subject: (.*)$/
SUBJECT=$MATCH
cc "| ( $REFORMAIL -r -t -I\"From: $UI_Name <$UI_Email>\" -I\"Subject:
Abscence Notification ($SUBJECT)\" -I\"Errors-To:
[EMAIL PROTECTED]" -I\"Precedence: junk\" -A\"X-Loop: $BADLOOP\" ; \
echo \"$UI_VacationMessage\"; \
) | $SENDMAIL -t"
}
Maildrop has to be your delivery agent, and the variables have to have
something in them... thought the concept might help you get started.

RE: [courier-users] Relay limiting
Hey Arturo... I think you haven't found what you are looking for cause you are looking for the wrong thing ;-) Acceptmailfor determines domains your server will accept mail for DELIVERY - not for relaying and retransmission. You probably need to write your own filter such based on the courierfilter global mail filtering setup. There are a few ways to do this - even PERL - then you can scan each message on arrival (during the smtp dialog) and see if it matches your domain or any one of your domains or maybe exactly the domain of that user - then you can reject it before it is accepted. You would need to be aware that this filter is called regardless of whether or not the user is authenticating it, so you will have to make your filter sensitive to the state of RELAYCLIENT or something so you don't apply the rule when you are receiving mail for local delivery... I bet there would be many people interested if you wrote such a filter - interesting idea - I think I would like it too ;-) m/ > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Arturo > "Buanzo" Busleiman > Sent: Monday, May 31, 2004 1:45 PM > To: [EMAIL PROTECTED] > Subject: [courier-users] Relay limiting > > > I run a webmail service for 4k+ users.

RE: [courier-users] Limit sending mails to 1 per minute / user? Stupid idea?
> is it an unrealistic or unintelligent approach to limit the amount of > mail that can be sent with a server? Don't think that would work for a variety of reasons... Many users read their email, reply and press send, but the ACTUAL sending occurs every few minutes in batches - what happens - they get deferred or queued? Assuming they are queued, client A sends interoffice mail to other users and gets huge delays on sending? Don't think it would make anyone happy. We log our mail sent, and process the logs to catch abusers. We virus scan to prevent spread of viruses... We restrict users from submitting mail through webscripts without authentication... No abuse so far. Our AUP says we'll cut them off and they know it. Just my 2 pennies. m/ --- This SF.Net email is sponsored by: Oracle 10g Get certified on the hottest thing ever to hit the market...

RE: [courier-users] RE: spontaneous maildrop error? error writing to mailbox
Thanks Gord... A pipe | is considered a mailbox delivery. Didn't realize that. Should have - screwed up in a similar way before. The program was puking, and as a result, the delivery was failing, but for some reason wasn't seeing errors... when I added -V 1 to the maildrop, the name of the offending program was output though - which made it easier to track down and fix. Strange thing was that my maildroprc file contained an echo, which wasn't being logged even though logically it MUST have been executed. m/ > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Gordon > Messmer > Sent: Tuesday, May 04, 2004 3:42 PM > To: [EMAIL PROTECTED] > Subject: Re: [courier-users] RE: spontaneous maildrop error? error > writing to mailbox > > > Mitch (WebCob) wrote: > > > > > which would imply that for some reason my Maildir is being > recognized as an > > mbox?!?!? > > Or that your maildroprc or .mailfilter file has a "to" or "cc" which is > directing mail to a mailbox file rather than the Maildir.

[courier-users] SA bug effecting courier... some help needed from a perl Guru - the SA guys are listening (Thanks Theo)
http://bugzilla.spamassassin.org/show_bug.cgi?id=2906 I reported this a long time ago, basically, the courier received line does not match the tests applied by Spam Assassin... this results in false positives on thinks like SORBS and DYNA_BLOCK for your own authenticated users... I've seen numerous courier users complain about this, and the suggestion to them is to reduce the score of various rules, which unfortunately reduces the effectiveness of SA... I'm not a PERL guy. Some experience with it, but not enough... Got this message from Theo - it seems that the SA developers use different mail servers, and would need sample headers, and cooperation from courier users to test... it's on the list for 3.0, so if someone wants to help, would be nice for everyone to be able to use those rules again. > > I'm not sure why this keeps getting pushed out - is it a big > problem?

RE: [courier-users] esmtp auth off by default?
I've never changed anything that I'm aware of to have auth used to allow relaying... Forcing AUTH for all smtp traffic would effectively disable the server from receiving mail from anyone unless it comes from another mail gateway smart enough to authenticate. So that part was left "off".

Could send you a patch that allows maildrop to autocreate missing folders...

RE: [courier-users] delay in HELO response
Am willing to entertain the idea, but why? Are response times that different in practice? Or can a simple baseline be established based on your connectivity in general... a threshold PER connection is probably a lot more work to test than a threshold per server, and I don't see volunteers yet ;-) So you'll have to justify the extra work to whoever volunteers to fix the problem. Would probably be easier to print time TAKEN if threshold is exceeded.

Totally simple! See what Sam is saying is that you CAN change the message file as long as none of the key information changes location... so as long as headers remain the same size, the content can change... as long as body parts remain the same size, content CAN change. So if we use submit to add the headers, before the structure is built, and just pad them to the largest size to be used, then we can edit them inside a filter without effect on courier. e.g. add: Spam-Status: XXX Replace with: Spam-Status: yes OR Spam-Status: no_ The same could work for anything that desires to add a header to flag a status on a message without resubmission. The first hack would be to simply add a constant with whatever headers hardcoded (this is within my C ability ;-) The better hack would be to add support for a config file which would contain a template for all headers to add - could ideally be read as courier is loaded or as submit is run. I'm hoping there is someone C'ish enough to do this - or I can do the former, but the former certainly isn't polished enough for distribution. > >> I'm going to continue pushing for my "id" solution as part of the > >> "Received:" header.

Would still be interesting to see what happens... and as I indicated in the bug notice I forwarded to the courier list... SpamAssassin ack the problem, but keep putting off the fix for courier... if anyone interested in courier is PERL friendly, it would be a good thing to get fixed. If your change makes the Received header more like an Exim receiver header, then it might fix the problem already - worth testing... an indication of the problem is triggering the dynablock rule on mail submitted through the courier server.

RE: [courier-users] delay in HELO response
I would expect courier itself is having problems doing the reverse lookup... iirc, courier doesn't use your local resolver, so it does its own DNS. Try turning off revser lookups and or ident - see where your problem lies. There was discussion about this before, Sam wanted performance in the reverse lookup - of course if the firewall restricts outbound queries or doesn't do stateful allows on outbound UDP you could have a problem. Unless you need it turn it off?

RE: [courier-users] [PATCH] reformime: return exit code of external program
I came up with something a fair bit leaner I think - seems to work for me.
Now I based this on some code someone else was talking about... and for the
life of me I can't remember where I put the name... so the credit doesn't
belong with me! but irrc, he didn't sign his work... I just made a few
tweaks, but here it is, and fixed some file handle stuff to make it work on
my system.
It runs as a perlfilter, so it's daemonized if I understand right - doesn't
get started and stopped, and is capable of rejecting the mail during the
SMTP process - so the remote server gets an error, and we just drop the
message.

RE: [courier-users] [request], please extende MAXPERIP options
I'm not sure, but I thought localhost was expempt from this limit, which would let you connect unlimited times if you went through a tunnel - alternatively, you could run two daemons - one for your webmail, and one for your other users - BUT, your webmail probably can't have any more connections than it has apache threads - which I doubt is 5000 (unless you are using persistent connections). m/ > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of > Miroslav Ris > Sent: Thursday, February 12, 2004 8:44 PM > To: [EMAIL PROTECTED] > Subject: [courier-users] [request], please extende MAXPERIP options > > > hi, > > thanks Sam for courier-imap server. > it's really best! > i am using this over 2 years. > > request: > please add per tcp/ip:netmask MAXPERIP options for courier-imap server. > > problem: > using webmail (squirrelmail and smm) for access to mail boxes (about 5000 > users, and set MAXPERIP=5000). > but same users use stupid M$ mail readers (MS Outlook Express and > MS Entourage). > this apps generate lots connections to imap server (one > connections for every > mail in local app cache) and server totally freeze. > > need set MAXPERIP for webmail server to 5000 and for all others to 4. > > thanks! > > -- > Miroslav Ris > > > --- > SF.Net is sponsored by: Speed Start Your Linux Apps Now. > Build and deploy apps & Web services for Linux with > a free DVD software kit from IBM.

RE: [courier-users] Prevent folder deletion
Hey Matt - I never realized the Trash folder was undeletable... if that's the case, I imagine that is hardcoded - you could look... and add your own folder. I do remember discussion of placing files owner by another user inside the folders to prevent them from being deleted. If you experiment, you may find a single file will cause the directory unlink to fail and the folder delete process to be cancelled. Don't know if this still works... haven't heard about this in a long time. m/ > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Matt > Sent: Thursday, February 12, 2004 1:40 PM > To: [EMAIL PROTECTED] > Subject: [courier-users] Prevent folder deletion > > > I have an exim router that automatically handles spam for virtual users, > by delivering it to a Maildir/.Spam folder.

RE: [courier-users] Message submission process (Re: Rejection/re-insertion methodology howto?)
Hey Sam - Thanks! I think I understand a lot better, and imagine others do too... And of course if it isn't said often enough - we appreciate that you have a day job too and that there are always priorities... Now, for those of use who want to hack... I have a counter proposal... First the long term (perhaps nirvana like) and then the short term hack. Long term, it would be nice if a filter could signal - perhaps by exit code, that the structure needed to be reread and reparsed before continuing. On returning a certain exit code, courier could know that an acceptance was given, but that the message was changed, and force an rebuild of the memory structure you mentioned, using the message file as source. There may be a more efficent way to do it, such as distinguishing between header only vs. body mods, etc., but at least this would make the reparsing overhead only a burden to those of us who need it - and it would still be better than resending - right? Short term hack: So we can only make a change if it doesn't alter the position or structure of existing data. That's the key. So lets do just that. Define a buffer size, intended to be large enough to record whatever information you want to modify in a filter Then, much like Lloyd has suggested, path submit. Submit will now create a new header: X-Filter-Info: XX You could of course substiture X for any character you like - so long as it doesn't break mail header standards. Then, you could wrap your arbitrary filter data in base64, pad with X's, and replace the old header installed by submit. No message structure alteration, and an editable payload. Could even be done multiple times as needed for diferent filters or purposes - create as many "place holder" padded headers as needed - in fact this could be done generically, by "including" this value from the config file - so that a recompile isn't needed to change the headers As submit starts it could append a value from /etc/addheaders to the message. Anyone like this idea? Gets us to the editable header stage a lot quicker, without as much overhead doesn't it? Would I screw something up doing this?

SpamAssassin looks at received headers and ALREADY fails to properly recognize courier's format - as a result mail received locally from an authenticated user is not detected as such and may be penalized for coming from a black hole listed IP I've submitted a bug report and been told that it MAY be fixed by version 2.70 - doing this could likely derail this header test again, so if you use SA you may have to code to skip it for locally authenticated users (which is probably an efficient idea anyways...)

RE: [courier-users] My Modest Proposal
Hi Lloyd. Would like to hear what others think including Sam - but it sounds like the best of a bad situation to me. I wonder how the effort and overhead you are making compare with a patch to courier that would allow modification of message files during global filtering. Although such an option may lower the efficiency of delivery perhaps if submitted as a compile time option it could be acceptable for inclusion in the distribution. Personally, I make my hacks as a last resort after trying to ellicit support, as maintaining them - particularly when dependancies on the core software may not be broken with future versions. I've seen people running filters twice to do rejection and modification separately - maybe before embarcing on this you might want to do some benchmarks? Just a few thoughts. m/ > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Lloyd > Zusman > Sent: Wednesday, February 11, 2004 5:21 AM > To: [EMAIL PROTECTED] > Subject: [courier-users] My Modest Proposal > > > In one or two other threads, I mentioned a Modest Proposal for a small > change in Courier.

1) there is no reason this would remain constant 2) as this value is only used locally, it wouldn't be that quick to leak (relative to other leaks of addresses 3) it would be very easy to rotate this regularly to keep it from being guessed 4) there would be a trail of received headers that could be used to validate it Don't think it's the best option, but this was the best idea when this was last discussed.

[courier-users] Help with an update to a little hack? Popping only some mail... Was working with .38 doesn't with .44.2
Hi.
I had a need to use pop to retrieve messages left in a subfolder of a
Maildir. I wrote a patch to the pop3d program in 0.38, and had no problems
for aobut a year... now after upgrading some of my servers I'm moving over
those users - I whip out my trusty patch and BANG - it doesn't apply, so I
go and create SIMILAR mods to the new file, and it doesn't work...
Does someone who knows more about the inner workings of this program have
ANY insight as to what I've missed?

The check of the new folder seems missing. Not sure what changed or how, but
my new patch seems to connect fine to an EMPTY mailbox, but returns the

fflush(stdout);

}
So obviously something has changed...
Any ideas?!?!? PLEASE and thanks...

RE: [courier-users] Re: Global filtering
There IS a way to do this, it's just a bit ugly (IMHO at least). Sam says the way is to run your filter and read the message file - do any rewriting you want to, and inject a new message. The control file can be modified to indicate successful delivery of the first message, the new message injected with modified content will take it's place. I understand the process, but I have a hard time understanding why this is better than allowing a filter to modify the message. I also have a hard time understanding WHAT exactly in the message is "cached" (the reason that direct modification of the message won't work according to what I recall from Sam's explanation was that there were things in the courier process that were not re-read from disk during the delivery process...) Maybe someone should just try it? Or try the reinjection method suggested by Sam. No database required. Use the existing filter model. m/ --- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.

Ok... my 2 pennies (still only worth 1.75 pennies cause I'm Canadian) I don't know python, but assuming maildrop is your delivery agent wouldn't you be better off doing any easy accepts in maildrop before calling out to another program (save compile, load and exec... etc.) I can't argue for or against - just asking. m/ > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Lloyd > Zusman > Sent: Sunday, February 08, 2004 6:37 PM > To: [EMAIL PROTECTED] > Subject: [courier-users] Re: Definitive way to determine whether there's > been authorization? > > > Lloyd Zusman <[EMAIL PROTECTED]> writes: > > > "Mitch \(WebCob\)" <[EMAIL PROTECTED]> writes: > > > >> If the last received header (the one added by YOUR server says > AUTH, you can > >> trust it - otherwise it can be spoofed.

As anexample (based on some discussions with Gord) I now use this:
if ( $SIZE < 512000 )
{
i=1
foreach /Received: .*/
{
if ( $i == 1 && ( ! ($MATCH =~ /Received: .*\(AUTH:
[^)]*\) *by /)))
{
xfilter "/usr/bin/spamc -U

If memory serves, unless you specify no-ident in your tcp options, courier will indent query the remote connection for a use id associated with the socket. Some firewalls / servers don't run identd, others block it, SOME return a real user id, but many masquerade a "nobody" id for all users or allow users override the value returned. hth. m/ > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Lloyd > Zusman > Sent: Sunday, February 08, 2004 2:28 PM > To: [EMAIL PROTECTED] > Subject: [courier-users] Where does "ident" come from in the courier > logs? > > > I'm curious about something: > > The following is a typical error line that shows up in my courier > logs (a single line, wrapped here for readability): > > Feb 8 17:23:51 myhost courieresmtpd: error,relay=:::163.21.15.248, > ident=hidden-user,from=<[EMAIL PROTECTED]>: 517 Syntax error > > Where does "ident=hidden-user" come from? > > Is "hidden-user" the HELO/EHLO value, perhaps? > > Thanks in advance. > > -- > Lloyd Zusman > [EMAIL PROTECTED] > > > > --- > The SF.Net email is sponsored by EclipseCon 2004 > Premiere Conference on Open Tools Development and Integration > See the breadth of Eclipse activity.

RE: [courier-users] maildrop(rc)
Not sure, but I think you'd have to chmod 666 your logfile - otherwise the
first user will access it but others won't - maildrop will be running with
the uid of the user being delivered to, so this would cause a problem...
other things might be permissions related as well...

RE: [courier-users] Interection PHP with courier
This may be a dumb question, but have you verified your environment is actually
being set?
Run something like `/bin/env` after making your calls to setenv, and check the
output?
Of course you'd have to do this from the web script and not from the command
line... Sendmail had some options (like overriding the from address) that
required the user id of the account attempting this to be in a config file of
trusted addresses I think - or something similar...
And php can be configured not to export certain env's too...
worth a check if you haven't already.

[courier-users] freemail as local mail forgery test?
Ok - any opinions on this? If I use the freemail structure to reject mail claiming to be from my local users if they are relayed from anything other than my mx's ... any problem with say 500 - 1000 entries like this? Or is there a better way or an existing method or a patch to regard all hosted domains like this? Would allow me to whitelist my own domains and users without opening the dor to forged froms in spam... All my users are advised to use my smtp or msa ports with authentication.

Proper handling of SENDER with TMDA in maildroprc - WAS RE: [courier-users] Re: Does courier / maildrop unset SENDER if it's empty?
I object to the word stupid, particularly because I think you are missing
something - there are valid reasons to process messages with no sender - but
there ARE some that don't need to be processed... I think I see what you are
saying...
Maybe I'm doing something DUMB here... maybe I'm running tmda when I don't
need to in this case - I think I see what you are saying, but if I change it
to not run for enpty SENDER, then a spammer sending mail from <> won't be
processed - right?
Neither would a bounce (generated by TMDA to a non-existant remote user)
Here is the code at present:
LOCKTMDA=$HOME/.tmda.lock
flock $LOCKTMDA {
SH_SENDER=escape($SENDER)
cc "| env SENDER='$SENDER' /usr/local/tmda/bin/tmda-filter"
if ($EXITCODE != "0")
{
EXITCODE=0
exit
}
}
#continue processing if TMDA approves message
Currently, if EXITCODE !=0, then tdma-filter has done something with the
message... I don't need to deliver, so I set my EXITCODE and exit
If it IS 0, then I should continue to deliver it.
Are you proposing I bypass TDMA when the SENDER is empty?
Would that allow bounces through?
Would it allow UNWANTED bounces through?
Currently TMDA eats bounces generated by it's confirmation messages, but I
wonder if it won't also eat bounces that the user may want to see... I might
have to try to force that to see...
Thanks

> This is probably not what you wanted to hear, but it's how I feel. > No worries man - this is a discussion list - everyone is entitled to opinion and comment! I'm not saying I'm right... I just look at the number of "glue" processes on my farm and try to eliminate waste. With each and every message delivered requiring multiple calls to external processes which each result in a shell, and a process which is memory and CPU... every time we pipe a file through something as simple as "cat" - which is the simplest of all no-op pipes (probably not but it will do for this discussion), it's another seat of descriptors, reads, time slice allocations buffers to manage and so on - it all adds up. I hear where you are coming from - and agree sometimes simple is better, but from another point of view eliminating unneeded processes and pipe is simple too...

Alternate filtering possibilities - WAS RE: [courier-users] deleting messages reviewed...
Okey dokey - from the top ;-) I first was trying to simply do "to /dev/null". I realized this didn't work, but to "|cat >/dev/null" did The reason (from the logs) was that maildrop was treating /dev/null like an mbox file. iirc, procmail doesn't lock unless you force it to (at least it didn't a while back) - which meant it could deliver to /dev/null no problem, and could do an mbox file without conflict IF you remembered to add the lock call (failing to do so seems to work but can result in mail loss during simultaneous deliveries, so kudos to Sam for eliminating that problem... What I realized from this is that how maildrop flock's everything is what prevents it from delivering to a file socket or a character device. If a test were done prior to the lock call to see if the handle points to a socket or a device, and if so skip the lock, then maildrop could communicate with filter daemons directly with no need to have a calling stub (like spamc) run interferance. So what started as a search for a way to sh!tcan mail, has lead me to a curiousity about what some of the more experienced users might think about enhancing the locking smarts in procmail to allow direct connection to file sockets & character devices - could open some doors... Did I explain that better? m/ > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of Jon > Nelson > Sent: Wednesday, January 14, 2004 1:18 PM > Cc: Courier Users List > Subject: RE: [courier-users] deleting messages reviewed... > > > On Wed, 14 Jan 2004, Mitch \(WebCob\) wrote: > > ... > > > You were against a "special case" patch for dev-null - which I > agree is not > > needed now that I know the "one true way"(tm) > > > > What I was pondering was a general patch which would make > communicating with > > filter daemons (listening on file sockets or char devices) > possible - and > > that would be to skip the locking in these cases where it has > no point - it > > would have the side effect of allowing /dev/null to work, but > that's not my > > point here...
