Thanks for the post. I've checked my setup - the guest is not set to sync with the VMware host. NTP is running with local clock server commented out & 'tinker panic 0' set.
It sounds like this is not a Dovecot issue so I'll stop posting to this list now and seek help elsewhere.
What negative effects to Dovecot would I expect to see where the system clock is constantly changing?
