Our queue is growing due to failed smtp connections. There are two main reasons:
(1) there is an smtp server but it's refusing us to connect to it, and (2) the
domain has no smtp server to connect to. See below for examples. The queue keeps
growing and syslog is reporting a lot of
"Sorry,_I_wasn't_able_to_establish_an_SMTP_connection."
Can anyone please advice what to do?
Thanks,
Fred

Sometimes I look for an alternative host in this domain or the parent
domain that accepts the mails - then I establish an entry in smtproutes.
Some annoying newsletters that don't accept bounces or are not reachable I
block via badmailfrom (if the bounces are the problem).
It all depends on your policy. You also could simply wait until the mails
bounce. Often the problem goes away after hours or days.

Tell my managers :-)
I agree, it's just that the delivery of emails is already getting delayed
by hours just because of these failed connections. It's mainly bounces
from mailing lists.

Okay: a growing queue is not a problem in and of itself. qmail deals
very nicely with a large queue. If you handle such a volume of mail
that the queue is usually large (<25K separate messages), then you
should change conf-split, recompile, and reinstall to /var/qmail2.

If mail is not being delivered obviously something is wrong. It's
sufficient for you to verify that the problem is not on your end,
unless you're really into sysadmining other people's machines for
them just because you have mail to be delivered to users there.

Mail is being delivered fine locally, but kind of struggling remotely
due to a large amount of bogus/unconfigured remote domains.
We have about 10K messages in the queue now, where qmail is
failing to deliver to remote domains such as these three (to mention
just a few, I can give you many many more domains). The problem
with these are missing MX records:
163.com
amanda.elsitio.com
21f.com
The second problem is SMTP servers which are down, such as this
one (again I can give you a list of many such servers):
rexx.riskymail.com

Which shows that they've appropriately chosen their domain
name. :-)

Hello everyone.
We are presenlty looking for a way to redirect
incoming mail to a second mail server were implementing. We need to do
this on a per user basis.
Is there anyone out there who has done this
before? If so, we would appreciate the help.
Thanks

See my cookbook for different domain handling issues.
There are several scenarios there.

VM is a web-based email client:
http://www.mintersoft.com/products/visualmail/index.html
It works fine when using sendmail as the SMTP server. And, of course, qmail
works fine apart from VM.
But when using qmail as the smtp server for VM, AND subsequently reading
the mail in VM, there are two problems:
1) Date corruption
2) Missing messages
I've approached mintersoft regarding this, but I'm not optimistic that they
will be both willing and able to fix it. So, I'm looking for workarounds.
I'm assuming that the date problem is caused either by qmail using GMT or
else by VM possibly neglecting to add the "Date:" header. What's the best
way to pin down the cause of the ploblem, and then how to fix it?
Regarding Missing Messages, I'm wondering if this is caused by the date
problem (above), or perhaps by VM neglecting to add a Message-Id header.
Again, what's the best way to pin down the cause of the ploblem, and then
how to fix it? Is it to reroute through qmail-inject, as per:
http://cr.yp.to/qmail/faq/servers.html#network-rewriting
?
Thanks, folks.
Dave
__________________________________________
NOTES:
>From qmail-header:
STAMPS
Every message must contain a Date field, with the date in
a strict format defined by RFC 822. If necessary qmail-
inject creates a new Date field with the current date (in
GMT).
Every message should contain a Message-Id field. The
field contents are a unique worldwide identifier for this
message. If necessary qmail-inject creates a new Message-
Id field.

any sign of problems in the log files?
You might want to use recordio from the ucspi-tcp package.
Is the message loss reproducible?

Well, qmail doesn't care.

Why not just copy the Content-Type header that's in the email itself?

Because that may not match the character set used to display the rest of
the page.
The real problem here is that currently there is no way in HTML to have
multiple character sets on the same page.

Thanks. I estimate that some time in May 2001 I'll have some free time to
learn how to grok unicode.

Yes. The problem might be the time spent in the kernel part of
the filesystem code.

I don't know what is the operating system in question (if it
was mentioned, I'm sorry), but reiserfs could also help...

We're having a really strange problem with qmail-smtpd. We're running it
with tcpserver so we can allow selective relaying, which works beautifully.
One of our users, however, cannot seem to connect to our mail machine via
smtp, at least, he can't connect from one particular program. He uses
Netscape mail, so I know smtp is working from his machine (ie, it's not a
relaying issue), but from this particular database program, he gets an error
every time he attempts to send to/through our server. Sending to a user at
another location (using that same location's smtp server) works fine.
I think there's a problem with the software he's using... could it be the
Bare LF problem? I know I haven't been able to supply much information here,
but that's because I can't seem to find log entries (apparently qmail-smtpd
doesn't have any), and I'm not sure how to continue. Any similar experiences
or suggestions for a course of action? Thanks for your help...

You can use recordio from the ucspi-tcp package to record the entire
conversation from that database application. Then you'll know if it's a
bare LF problem or something else.

Hi,
I would like to know where the bounced mails reside when I
send it to the wrong address in Qmail using Vpopmail.
Could anyone let me know which directory the mail goes to when
bounced.
Thanks

The default vpopmail installation does not bounce mail back to the
sender if he tries to send to a non-existent user. Instead, the mail goes
to the postmaster account.
To change this, you should edit your
~vpopmail/domains/<domain>/.qmail-default file, and put bounce-no-mailbox
instead of the postmaster directory as a parameter to vdelivermail.

Brian

Hi there,
I am a qmail newbie so please correct me if I am wrong.
I am running qmail-1.03 with the default settings of
tcpserver -c 40 ( for smtp connections )
concurrencylocal 10
concurrencyremote 20
When I checked the logfile, I found there are a lot of
"status: local 10/10", "status: remote 20/20". and also
many "tcpserver: status: 40/40" messages.
My guess is it means that there are always many mails waiting for
qmail-local and qmail-remote and many smtp requests waiting for
connections. Am I right ?
I understand there is no single optimal setting for
all machines but am wondering if there is any good way to find the
right setting for my server.
Any idea ?
BTW, I'm runing it on a SPARC box w/Solaris 2.6.
Thanks in advance !

You can set the DATABYTES variable from tcpserver, just like RELAYCLIENT.

Hi,
OK - this means that I can add a line as follows into /etc/tcp.smtp :
192.168.1.:allow,DATA-INTERNAL=""
and have a control/data-internal file with the databytes limit set??
Please advise

No.
Instead, try:
192.168.1.:allow,DATABYTES="1048576"

Expanding on the work of the infamous [EMAIL PROTECTED]
(infamous, that is, because no-one knows his real name :), I have
come up with a set of patches to qmail and checkpassword that let
you have virtual POP3 users in a MySQL database. For more details
hop over to http://iain.cx/unix/qmail/mysql.php, just don't mention
the invisible menus and headings - I'm having a problem with libttf.
-- blurb follows --
Why would you want to use my patches over takeshi's? Because
you can do more stuff. Everything that qmail and checkpassword do
that's related to local mail delivery can be stored in the database.
This means virtual domains (rewriting [EMAIL PROTECTED] to
[EMAIL PROTECTED]), receipt hosts (rcpthosts table complements
control/rcpthosts), .qmail aliases (associating alias-root
with the virtual user "mail4root"), mail(dir|box) ownership
(qmail-getpw bigcompany-sales returns
bigcompany\0800\0100\0/popmail/bigcompany\0-\0sales\0) and POP3
authentication (bigcompany can read mail). The latter can use
encrypted, MySQL-hashed or plaintext passwords.
You can also do crazy things with judicious database hacking,
including giving real system users separate POP3 passwords by
putting their real uid, gid and home directory in the mailbox
table (haha, they may sniff my mail password but they still can't
login as me via ssh) and have mailing lists by putting several
entries in the alias table. I admit I need to document this
more: documentation is work-in-progress at the minute but there
is at least something on the web page.
Perhaps the most significant feature is that I've tried to
stay in the qmail spirit by providing loads of error checking so
for example if the MySQL server goes down (and we all know that
they don't) or if we can't alloc our strallocs, the various tools
will return 111 and try again later. Please audit my code and
tell me if I'd made any howlers.
All of this has been tested on Linux 2.2.1[024] and
FreeBSD 3.[13] but feedback is always welcome.
