Problems with IMAP Login for domain aliases

[Shane Mc Cormack]

We have an issue with one of our plesk nodes where imap users are no longer able to login using their domain aliases, only their mail domain.

Looking in /usr/local/psa/var/log/maillog I can see the following for any would-be successful logins (password given is correct):

Aug 23 09:21:13 plesk51 imapd: IMAP connect from @ [127.0.0.1]chdir "/var/qmail/mailnames/aliasdomain.com/test": No such file or directory
Aug 23 09:21:13 plesk51 imapd: IMAP connect from @ [127.0.0.1]chdir "/var/qmail/mailnames/aliasdomain.com/test": No such file or directory
Aug 23 09:21:27 plesk51 imapd: IMAP connect from @ [127.0.0.1]chdir "/var/qmail/mailnames/aliasdomain.com/test": No such file or directory
Aug 23 09:21:27 plesk51 imapd: IMAP connect from @ [127.0.0.1]chdir "/var/qmail/mailnames/aliasdomain.com/test": No such file or directory

If the login details given are incorrect, this is not added to the log.

After searching I discovered: http://forum.parallels.com/showthread.php?t=97541 which suggested running:

/usr/local/psa/admin/sbin/mchk --with-spam

and

/usr/local/psa/admin/sbin/autoinstaller --select-release-current --upgrade-installed-components

which has not fixed the problem.

As a work around I have done:

ln -s /var/qmail/mailnames/realdomain.com /var/qmail/mailnames/aliasdomain.com

Which has fixed the problem, but I'm sure this is not the correct way of solving this.

Any other suggestions you can offer?
