Hello,
We have one user who is complaining that he has lost mails from 3 imap
folders, administered through squirrelmail.
The folders suddenly appeared unregistered, and once manually
registered they were empty.
Has anyone observed something like this?
We are running two servers (as VMs) with Dovecot v2.2.18, synced
(two-way) using dsync. The configurations follow.
Can you please help me understand what may have gone wrong?
Can I try to find actions regarding these folders in the logs? What
should I search for?
Could this be an issue involving dsync? How can I trace back dsync
activity in detail?
Server configs follow (I have only altered the real domain name and
the login greeting.)
Thanks in advance,
Nick
