I seem to have broken things really bad. I tried to make mail.domain.tld
an alias of domain.tld
Now authentication only works from time to time.
The bounce says:
<u...@domain.tld>:
Sorry, no mailbox here by that name. (#5.1.1)
Of course, that account exists.
Where are domain aliases stored? Can I manually delete a domain alias?
I'm using vpopmail 5.4.17 with users stored in a cdb file.

This most probably is not a vpopmail problem, but a chkuser one.
The support page of chkuser
(http://www.interazioni.it/opensource/chkuser/support/mailing_lists.html)
points to this mailing list, so that's why I'm posting this here.
chkuser is simply using basic qmail checks, giving a better log. It
is giving back what qmail would give back.
Check carefully qmail configuration and files availability.
nothing changed between the two events (rejecting a legitimate
message and allowing a similar one)
all files are world-readable, except the .lock files
The mail server in question runs:
netqmail 1.05
vpopmail 5.4.17
chkuser 2.0.8b
simscan 1.1
install chkuser 2.09, has more checks, new features and solves minor
bugs (not related to your question).
hard to do on a production server. I've set this one up more than two
years ago, and I remember there was a rigid order in which patches
were supposed to be applied to qmail, and some of them had to be
manually added (thinking of simscan, smtp-auth, chkuser)
It should be easy. Copy new chkuser files over old files, check
chkuser_settings.h (some have changed) and recompile.
In the meantime, I've googled a bit and found an alternative. I'll
post a "what's your experience with ... ?" message later about it.
Messages sent to existing and not overquota users on this server
randomly (as far as I can tell) are rejected with this message:
Remote host said: 553 sorry, that domain isn't in my list of
allowed rcpthosts (#5.5.3 - chkuser)
I've checked and double checked that the user exists and there was
no typo when entering the destination email address.
Sending again after a while to the same user ends up with the
message into his mailbox without any issues.
The server's /var/log/qmail/smtpd/current log file shows this about
the rejected message:
2009-07-24 12:28:19.035629500 CHKUSER rejected relaying: from
<sender's_email_address::> remote
<remote_mail_server:unknown:remote_ip> rcpt
<valid_u...@mail.domain.tld> : client not allowed to relay
The mailboxes on this machine are all respecting this pattern:
u...@domain.tld
You say general pattern is u...@domain.tld, while log says
u...@mail.domain.tld.
Are you sure 100% domain names do not include blank, DEL, strange
not visible chars? It could happen when spaces or strange invisible
characters are inside mail addresses.
Yes, the recipient mail address I've typed correctly (I
double-checked it, having faced stupid users before who think that
spaces in email adresses can't hurt that much, can they?)
Basically, i replied to a user on that server and got the bounce back
imidiately. Cursed at the binary gods for allowing functions to
return different results when fed the same input, had to leave the
office, and when i got back replied again to the same message,
checked and it arrived in the users's mailbox. The log shows this:
2009-07-24 18:09:48.389030500 CHKUSER accepted rcpt: from
<my_email_address::> remote <my_email_server:unknown:my_ip> rcpt
<u...@domain.tld> : found existing recipient
Check if any limit is reached. Like max open files or max MySQL
connections. It could happen in a peaik moment you reach some limits.
chkuser version you have does not handle mysql refused connections,
while 2.0.9 does.
What i don't understand is why vpopmail is sometimes being asked to
authenticate /u...@domain.tld/ and sometimes /u...@mail.domain.tld/ ?
probably some users put the wrong username in Outlook... missing the
domain part, so automatically you have the "me" file added to
address... or?
Ciao,
Tonino
Of course, possible solutions to my problem are:
1. getting rid of "mail." part completely
2. making mail.domain.tld an alias of domain.tld, so both would work
Thanks a lot for any ideeas you might have.
Regards,
Tonino
The /var/qmail/control/me file lists this: mail.domain.tld, which
is also the MX for domain.tld
/var/qmail/control/rcpthosts lists both domain.tld and mail.domain.tld
/var/qmail/control/virtualdomains shows domain.tld
/var/qmail/control/locals shows only mail.domain.tld
/var/qmail/control/defaultdomain only shows domain.tld
What could be wrong, but most of all, why is the error occurring
only rarely (but often enough to be annoying)?
Thanks in advance for any answers you might be able to provide.
