There's a mix of the following: Outlook Outlook express Thunderbird Squirrelmail (webmail)
But we tried getting the users sharing the account to use just one client (squirrelmail) and they were still reporting the problem?!
I forgot to say that they were working this way with no problems on dovecot 1.0.2 but since the migration to 1.1.3 we've had this problem.
In an effort to help the situation I changed the following settings from the original, from enabling lazy writes to disabling: mbox_dirty_syncs: no mbox_lazy_writes: no
As long as you're using Dovecot's index files, these should make no difference. Do they?
I find this problem really weird. If you're using a shared account, it's exactly the same as if there were just a single user using multiple clients. Or in Squirrelmail case the same as if the same user was logged in multiple times with different web browsers. And in Squirrelmail case it connects, does something for a short time and disconnects. Dovecot doesn't even know if there are different users using it. So if it shows different views for different users, then the exact same thing should be happening also randomly to the same user even if s/he's the only one logged in.
Are you using any kind of an IMAP proxy?
