I had the same problem. If you are running dovecot on a virtual machine this is what I did and the issue was fixed:

AFAIK, to keep good time on a linux machine inside the network, you need to run "ntpdate" and not "ntpd". No no no! That just makes things worse! It's the most common reason for these "Time jumped forwards/backwards" warnings.

Seriously ?
Definitely you should run ntpd -- but you need to make sure that it's configured correctly and working. Running "ntpdate" will cause time to jump.
I thought everyone knew that if you removed the 1.55v watch battery from the motherboard, you could put in a 1.6v battery and time will run faster. Then just use ntpdate - time will never jump forward, and dovecot won't crash.
:D
