Hmm.  I can't think of why dovecot wouldn't time out.  I think maybe
the problem is with your webmail system -- it's not detecting when a
client connection goes away and releasing all the resources associated
with that user.

This is not a typical problem though -- most webmail software do not
keep persistent IMAP connections open during a session unless they use
some IMAP proxy.

Are your IMAP connections connected to the webmail server or an IMAP proxy,
and is that connection active (despite webmail user disappearing)?
