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?
