Package: dovecot-imapd
Version: 1:1.0.15-2.3
Severity: important

Dovecot imapd terminates itself deliberately if the system clock moves 
backwards.
This is the same underlying issue as bug 420175, but that was a laptop after a 
suspend and was deemed unimportant because of that.

This occurs on a XEN based virtual private server at a commercial hosting 
facility.

Jan  7 04:54:49 xxx dovecot: Time just moved backwards by 81 seconds. This 
might cause a lot of problems, so I'll just kill myself now. 
http://wiki.dovecot.org/TimeMovedBackwards

A timebomb like this renders dovecot unsuitable for use on servers as all email 
clients
will be unable to connect to the mail server until an administrator discovers 
the problem
and restarts the mail server.

The upstream wiki mentioned in the syslog message suggests runing ntpd on a XEN 
domU can
cause this. This is not the case with this occurence. No ntp or clock setting 
code
is running in the domU.

Upstream appears unwilling to address the problem, per the same wiki page.
They never want a file to have a timestamp in the future. I'm not sure how
stopping protects from that, but that is their position.

Possible resolutions could be:
  - wrap the dovecot daemon in a script that restarts it in this case.
  - warn administrators that they are installing a fragile solution during 
install.
