Perhaps the mailbox is corrupted, so message two is causing the pop server to hang, crash, whatever. No, the pop server does not hang. After this "QUIT" message the client disappears. The next connection from the same client (or from any other client) works normally - client can fetch at least one email. Often everything looks "normal" - i.e. for each command there is a normal response from the server. But sometimes the server does not respond at all in the middle of a session (without beeing hung or something). Error log does not show any errors, so I guess the mailbox data is not corrupted. I have some error messages of the kind "mailbox locked" (can not look up the exact message right now), but this does not seem to be related to the other problem (because of different times when this happens). Or maybe this IS a possible reason somehow?
