[Dovecot] Dovecot 1.1.10 and chroot

[Michal Soltys]

As it's been a while since I upgraded (1.1rc10, jump to 1.1.10), this 
might be present in earlier versions as well.

Anyway, if one enables mail_chroot in global config file, dovecot will 
try to access /tmp there. Per-user overrides behave correctly.


For example, with:

mail_chroot=/home/vmail

dovecot will abort with:

Fatal: chdir(/home/vmail/tmp) failed with uid 65534: No such file or 
directory
Error: imap dump-capability process returned 89
Fatal: Invalid configuration in /etc/dovecot.conf
