Quoting Eric Broch ebroch@whitehorsetc.com:
I have dovecot 2.0.11 installed on a CentOS 5.7 email server. Two of the server email clients, one using Outlook and the other Thunderbird, have had all the contents of their inbox disappear only to reappear at a later time. One client's inbox email reappeared upon receiving a test email (to check if it would show up in the inbox) from another user. Has anyone heard of such a thing?
After a recent upgrade - I've had an issue with an older version of
Horde not displaying the INBOX. I've gotten it to restore by removing
custom Sorting options. I upgraded Dovecot, the backend server, and
PHP all relatively recently, but having only seen it with my older
Horde install I figured it was a PHP issue.
Just for giggles you could ask those users to use a different Sort method..
