I have shown respect for DJB and everyone on this list. I am looking very

going to show itself to be superior to BIND.

BINDthinkers cannot just jump blindly into djbdnsthink. There are going to 
be a few posts now and again where someone is going to show a few zone 
records to clarify their point while they transition into qmail/djbdns/etc.

Noone should say: please don't post BIND zonefiles to Dan's lists. This

request to Charles not to shut down this kind of information and received 
arguments from Charles which I responded to. In the process of responding to

Ignore the tests you did; they're worthless, and tell you nothing about

not setting the RELAYCLIENT environment variable for random IP addresses

Some people may have private domains that they don't wish to disclose. These

Certainly software that does this is broken, but it's also perfectly legal 
for
first%last@host1 or first!last@host1 to be delivered to an account on that

Re: SPAM Patches recomendations.

2001-05-03 Thread q question

What should convince you to ignore those tests is that they are providing a
diagnosis (Relay attempt succeeded) which is patently false (it isn't a
successful relay unless the mail makes it to the final destination, and 
they
aren't even actually sending the mail, just testing the RCPT TO: command).

Charles

Relay test 7
MAIL FROM:([EMAIL PROTECTED]@mail.mydomain.com)
250 ok
RCPT TO:(nobody%prodigysolutions.com)
250 ok  (Failed Test)
RSET
250 flushed

Relay test 13
MAIL FROM:([EMAIL PROTECTED]@mail.mydomain.com)
250 ok
RCPT TO:(prodigysolutions.com!nobody)
250 ok  (Failed Test)
RSET
250 flushed

I see your point, the (Failed Test) occurs immediately after
RCPT TO: ...
250 ok

This is why your (and Chris's) explanations about the assumptions are very 
useful, that the mail could be successfully received either for a local 
delivery, or for a relay, or perhaps not delivered at all.

'Proof'? If the relay test in question was acceptable, the OP would already
have proof. A proper relay test involves the _actual receipt of relayed
mail_. Try your own relay test, if you have addresses at multiple domains
available, along the exact same lines as the 'tests' performed by
prodigysolutions[1]. If you don't have another address available, use a
friend's email account. If you manage to relay third-party mail through a
qmail server with rcpthosts populated only with domains that you should
actually deliver for (present in locals or virtualdomains[2]), and a
properly set RELAYCLIENT environment variable, I will eat a bug on camera, 
and
give you links to watch it on the web. :)

[1] I didn't recall seeing recent results for the
'user@destination@relay' test, so I did them myself. Delivery attempt is
to local user 'user@destination', which is unlikely to exist and in any
case is not a relay. The '%' and '!' garbage comes up at least once a
month, and is known _not_ to be a problem. Check that for yourself as
well, if you like.

[2] Or, of course, a domain that you're an MX for, but not the
best-preference MX.

 
  I do appreciate your reply and I realize full well that I may end up
  deciding to ignore the Prodygy relay test failures someday myself.

Avoid the rush! Start ignoring them today! 'Tests' which assume that
they know better than the MTA they are testing how it will deliver mail
are inherently broken. 'Tests' which do not actually attempt to deliver
mail anywhere, and do not only count the _actual receipt of mail_ as a
successful relay (failed test) are inherently broken. As far as I am
concerned, any 'test' that does not actually attempt delivery should
immediately be ignored.

Re: Can MX record be CNAME?

2001-05-03 Thread q question

Nope, mail.swishmail.com cannot be a CNAME if you want to point your MX
record at it.  It's forbidden.

And please don't post BIND zonefiles to Dan's lists -- they're meaningless 
to
anyone who doesn't do BINDthink.  Instead, tell us what's happening
(mail.foo.net is an MX record which points to mail.bar.org with distance 
10,
which has an A record of 10.20.30.40).  That at least means something to
everyone who understands a little about DNS.

1) I appreciated Kris's short excerpt from his BIND zonefiles. They were 
exactly what I needed to see to understand what Kris was saying about his 
CNAMES.

2) I find the sentence format that describes what is happening mail.foo.net 
is an MX record which points to ... to be more confusing than seeing the 
exact records.

3) The people that don't do BINDthink aren't going to understand either the 
sentence format or the exact record layout. I think people either know or 
don't know DNS, and they don't fall into a middle ground that can be 
addressed by the sentence layout.

4) You have stated repeatedly that people must provide detailed information 
in their emails to this list. Kris did so, and you protest that it is too 
detailed. You really can't have it both ways.

Re: Can MX record be CNAME?

2001-05-03 Thread q question

Which is pointless.  You can't receive mail without advertising the domain 
in
the DNS, so trying to hide the information here achieves precisely nothing.


That's not true. I've dealt with plenty of internal corporate email 
situations that are not exposed to the internet email. Not all email goes 
out on the internet.


Hiding the domain here just makes the job of list members tougher.  I
encourage everyone to ignore messages with falsified domain information or
logs.


I think everyone should be free to describe their situation using either 
generic a.b.c notation or valid domain addresses. Granted, if you are a 
novice, it is preferred that you use the valid domain addresses because you 
may incorrectly use the wrong generic addressing.

I didn't mean don't give us the DNS information.  I meant give us the

information in a format that does not require an intimiate knowledge of

After all, you don't need to know anything about BIND to be a knowledgable
mail admin.


Actually, I think I could never have solved the sendmail configuration 
problems that I have solved without knowing BIND thoroughly. Mail 
administration maintenance doesn't need detailed BIND, but the initial 
sendmail configuration in a complex environment absolutely needs thorough 
DNS/BIND knowledge.


You just need to understand some DNS basics.  I, unfortunately,
have had to learn a bit here and there about BIND zonefiles, but I still
prefer the information in a non-proprietary format.  BINDthink is painful, 
and
in this list, completely unnecessary.


Charles, I understand what it is like to be somewhat familiar with something 
but not thoroughly familiar. There are so many technical topics that it is 
impossible for all of us to maintain a full level of expertise in everything 
at all times. Even once one has mastered a particular topic, it is quite 
easy to become rusty after only a few weeks away from the topic.

I understand that you are asking for the sentence explanation for those who 
are not into BINDthink. I think it is fine to ask for the sentence 
explanation and say this is helpful for those not into BINDthink.

Please respect those people who do understand BINDthink and realize that it 
is instantly more clear to us to see the actual records rather than to 
suppress the display of the actual records on the email list.

You do not own this email list. You are sharing this space with a lot of 
people who have a wide range of technical expertise in a wide range of 
topics.

Just because you prefer something in one particular way, does not mean your 
opinion must dominate.

I thought it was terrific when Kris showed the actual zone records. I'm 
happy if he wants to take the time to make a sentence summary of it to 
please you and others who may be hazy about DNS.

I was appalled when you said please don't post BIND zonefiles to Dan's 
lists. That is a blanket directive that is not necessarily shared by 
everyone on this list, certainly not me.

A few lines of zone records speaks volumes for BINDthinkers and they are 
well worth the space in the email.

 One last note on this thread. While rereading the FAQ, I came across this
 which indicates qmail has brakes to keep from generating denial of 
service
 attacks.
 
 http://cr.yp.to/qmail/faq/efficiency.html
 
 Does qmail back off from dead hosts?
 Answer: Yes. qmail has three backoff features: ...

Qmail backs off very well, but doesn't work all that well with
sendmail under heavy load.  The problem is that sendmail keeps
accepting connections even when it doesn't have enough system
resources to accept mail, and tends to thrash to death.  (Qmail
systems usually use tcpserver which enforces a maximum number of
simultaneous connections rejecting any beyond that limit.)  But since
sendmail doesn't reject connections, qmail can't tell that the
recipient system isn't responding.

Sendmail users tend to assume that anything sendmail does must be
right, and anything different must be wrong, so they often blame qmail
for opening too many connections.  In reality, the connections could
just as easily come from any other mail system, of course.

Hi John,

I hope you don't unsubscribe from this email list. You are not alone in 
spending days printing and reading and feeling lost. I'm really dreading my

Actually, I know sendmail really well. I saved one company from spending 
$100,000 on a software package to solve a Unix/PC email problem that they 
had on their internal servers by rewriting the sendmail configuration files 
on their Unix servers so they would be able to send email directly between 
their PC and Unix users. I've also solved a lot of other tough pure Unix 
sendmail configuration issues over the years that others couldn't solve.

But, actually I feel none of that sendmail knowledge is helping me with 
qmail, IMAP, LDAP, etc. To some extent it does, but not really.

I also don't feel the slow connection problem that is reported so frequently 
is addressed well in the FAQ. I respect the person who is simply putting a

Is qmail best reserved for mailing list server purposes only?

2001-04-29 Thread q question

One of the reasons I was interested in qmail was the security aspect of it. 
I've been impressed that noone has won the reward that is available from Dan 
Bernstein. This is probably the most negative comment I have seen about 
qmail while surfing for info:

http://www.orbs.org/otherresources.html

Qmail admins: Qmail's current version is secure by default, but earlier 
versions were insecure. Most admins know enough to follow the instructions 
for securing it before putting qmail into service, however it usually drops 
ORBS test messages checking for UUCP pathing vulnerabilities - ! pathing - 
into the admin mailbox. As ! is a standard network addressing indicator, 
this can only be charitably described as yet another Qmail bug. Qmail is 
extremely network unfriendly and generates denial of service attacks on 
other mailservers in its enthusiasm to deliver as many messages as possible 
in a short period of time. For this reason it is best reserved for mailing 
list server purposes only.

Do you all agree with this opinion that qmail is best reserved for mailing 
list server purposes only?

Russ, I appreciated hearing some of the background issues in communication 
difficulties between the ORBS and qmail groups.

John, I started to shrug it off when I read it because I had the exact same 
thought immediately that you expressed, which was why would an mta that 
supposedly generates denial of service attacks be especially suited to 
being a mailing list server? It seems to me that it would be especially 
UNsuitable for that task.

Jason, I agree with you that there is no real distinction between list 
subscribers and regular mail recipients. You can get an equally high volume 
either way, and not all lists restrict the members to text only emails. Some 
lists promote the html email, but these lists are of course usually not 
technical lists.

Thanks for the feedback!

Re: Is qmail best reserved for mailing list server purposes only?

2001-04-29 Thread q question

One last note on this thread. While rereading the FAQ, I came across this 
which indicates qmail has brakes to keep from generating denial of service 
attacks.

http://cr.yp.to/qmail/faq/efficiency.html

Does qmail back off from dead hosts?
Answer: Yes. qmail has three backoff features:

Each message is automatically retried on a quadratic schedule, with longer 
and longer intervals between delivery attempts.
If a remote host does not respond to two connection attempts (separated by 
at least two minutes with no intervening successful connections), qmail 
automatically leaves the host alone for an hour. At the end of the hour it 
``slow-starts,'' allowing one connection through to see whether the host is 
up.
Some mailers opportunistically bombard a host with deferred messages as soon 
as the host comes back online. qmail does not do this. Each message waits 
until the appropriate retry time.

Re: A news.newusers.questions's Guide to Qmail

Hi Brett,

I had no intention of correcting or offending you or anyone. If you'll note, 
I said a simple FYI. I did notice the difference in the article in which 
the list. was left off. I was just describing the the method that worked 
for me yesterday so that no one would feel that they needed to make the 
effort to test signing up again to see exactly what worked.

Regards!

Re: Receiving mail for multiple domains

2001-04-27 Thread q question

I agree that it is difficult to figure out the domain configurations. My 
favorite documentation on that at the moment is at:

How can I configure qmail to accept mail for mail.domaina.com and

Nothing in the FAQ could be found.

Thanks,
