Seems to be working fine. It's recursive, it's smart (subsequent runs
don't download the old messages again, only the new messages), the
command-line switches are a rich set that's pretty much
self-explanatory. It's easy to do non-destructive tests. It's flexible
Downside: If you have very large messages on the source IMAP servers,
you better run the script on a machine with lots of RAM. On my system it
died repeatedly with "out of memory" when it was hitting a 32MB message
(on-disk size), and the system has 1GB RAM.
It's probably best to run it on a 3rd system, one that's separate from
both the source and the destination IMAP servers, otherwise unpleasant
things might happen if the script starts to gobble up RAM on the IMAP
server. Again, this 3rd system is best if it has lots of RAM if you
allow large messages on your source IMAP server.
