This seems to be a bete-noir for the dovecot developer.  Whatever, it is
a royal pain in the arse, as my mailserver always steps the time
backwards on each reboot, and then dovecot does it's dying swan thing.

Three choices:

  * Don't run 'ntpd -g' as the documentation tells you is the modern and
    accepted method.  Instead, run 'ntpdate' as a separate process and
    run 'ntpd' without the '-g' flag.

  * Don't run dovecot.  Other IMAP servers do not suffer in the same

  * Put up with it.  Avoid reboots, and swear at all concerned any time
    you really do have to reboot.
