Well, I use SeaMonkey at home, maybe it has the same problem as 
Thunderbird:

If SeaMonkey is able to open a connection to the server, but then the 
corresponse stops, SeaMonkey seems to do nothing, although it waits for a 
transmission for eons.

I have this problem in conjunction with Cisco Firewall IDS stuff and some 
virus scanners that both stumble over STARTTLS. Sometimes when the 
internet connection gets very busy or down completely.

Can you trace the connections from your local client to the IMAP server, 
e.g. with Wireshark?

Bye,
