I would like to recommend imapsync, which lives at
It works great for fully automated mailbox transfers. It creates folders 
and copies subscriptions as needed, then drags all the mail across that 
isn't on the remote server yet. I've been doing this between Cyrus 
servers and from UW-Imap to Cyrus, with mailboxes up to 500MB in size. 
Imapsync on a SunBlade 2000 (1GHz) was able to fully saturate a 512kb/s 
DSL line. Imapsync is also very actively maintained.
