[Dovecot] imap-login ESTABLISHED client sessions not timed out by server
Good morning everyone,
I noticed some mobile client connections that I know should have
timed out at least 20 mins ago, yet these are still there. The device
in question lost its 3G connection and never re-established it. I know,
because in this case it was my 'phone ;) Why should the imap-login keep
the copnnection in in EST, when it was dropped ages ago. I imagine that
the mobile client did not correctly close down the session, but it
should have timed out on the server.
Any ideas? Has anyone noticed this afore?

But when not in IDLE, there's only 30 minute inactivity timeout (30 mins is minimum required by IMAP protocol).
