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 way. * Put up with it. Avoid reboots, and swear at all concerned any time you really do have to reboot. Cheers, Matthew -- Dr Matthew J Seaman MA, D.Phil.
