My setup is hMailServer 5.3.3 B1879 (last stable version).
I have some users using IMAP and some other users using POP3. Totally about 20 users.
Is all fine for most of them. Only one user is calling me about one time at month (this is the fourth) because he is experiencing "MAILBOX ALREADY LOCKED" problem. He is using only one client (outlook express on windows XP) on a desktop PC. No mobile phone or tablet.
Sometime it's mailbox will lock and there is no way to unlock, neither waiting one day without trying access.
Looking at log that's what I see:

The user is calling me...
So... it is evident that the problem begin with an unclean client logout (Session: 22681 does not QUIT).
But WHY hMailserver did not reset the lock automatically??? Must do it!
I search the forum for this problem. I see some similar thread in 2005, 2006, 2008 with older versions, but now in 2012 I hoped that this problem was solved.
Is there any workaround or any attempt that i can make for fix this behavior?
Pleas don't replay with "use IMAP instead of POP".
