Well, it would be nice to know what caused it. Could you enable rawlog
for those users (http://wiki.dovecot.org/Debugging/Rawlog) and show me
what was the last command from client that caused the disconnection?
It most likely shows in .out file something like:

123 FETCH 345 (...)

There are no complaints yet (although it is not limited to one user). It seems to occur with different clients (Apple/MacOS mail, Windows/Thunderbird, Pine).

We're running dovecot 1.0.10 on Solaris 10 with mboxes (NFS) and local index storage. There are no such messages before the upgrade (from version 1.0.5).

Hello, I still don't know the source or reason for that. Updating to 1.0.13 solved this issue (in my case). The BUG-messages disappeared.
