Hello,
after I have done a dist-upgrade to Squeeze, I got some nasty problem with my
dovecot.
When I try to establish a connection via IMAP, it doesn't react and writes
the following into my logfile:
2011-02-16 15:23:49 imap-login: Info: Login: user=<thomas at XXX>,

I tried to change privileges for /home/vmail/, didn't work. What makes me
wonder is the <unknown>-label after euid=5000.
Anyone an idea how to fix that problem?

Weirdness 2: stat() fails with ENOENT. Do you have SELinux or something enabled?

After all what has been said it sure looks like a chroot problem. Could you post the (exact) contents of the following command: grep 'vmail\|5000' /etc/passwd /etc/group /etc/dovecot/dovecot.conf As in Squeeze Postfix runs chrooted, I wonder, did you re-configured the postfix chroot (see /var/spool/postfix/) and put there all what you need to avoid chroot problemas while combining Dovecot +Postfix + MySQL? Finally, are shure that your VPS provider isn't encapsulating in chroot jails either your private configs in /etc/ or your stuff in /home/ ? M.
