Re: imap server not reopened after timeout

The very frequent dropped connections don't happen if I don't use TLS.
To summarize:

- they happen with TLS to port 143
- they don't happen with a plain connection to port 143
- they don't happen with a TLS connection to port 11143
- they don't happen if I connect using
    ssh jdc.math.uwo.ca dovecot --exec-mail imap

Very strange.

The main connection problems I have aren't due to an idle connection.
They happen whether the connection is under heavy use.  I can trigger
the drop 100% of the time by copying 20 or 30 messages from a local
folder to a remote imap folder.

At least I now have several workarounds.  The last one, using ssh, seems
to also be quite fast to connect, so I'll probably stick with it.

Thanks for the help,

Dan
