I didn't have these errors from home before, and still don't have it now, so I still think it has something to do with firewall, and courier configuration, You may be right, I have a fully-stateful-packet inspection Firewall (Linux and IPTABLES and other things) I do not have issue. I use it both ways home and work similar to you. If you want I can look at my courier-imap-ssl config. I think I tracked down the problem. Our company uses Cisco firewall, and reading some Cisco documentation, they have MAP (and other protocol) timeout, which means that firewall will disconnect the connection if it is idling some period of time (5 min default). So I set check for new mail to be every 3 minutes. Seems to work for now. Now I want to investigate if mozilla has other ways to keep connection alive.

I believe this defaults to 5. I decreased this to 2 and the server disconnects went away. Just checked at 5 again. After opening more than a few folders I get server my.domain has disconnected. The server has gone down or there may be a network problem. Lowering this value to 2 solves it (although the logic behind it goes 'woosh' over my head). Hope this helps.
