Did nobody ever see this? Also, I use imapsync to sync a 6GB
mail 
account from a LAN-local cyrus imap to dbmail over an
internet 
connection. Most e-mails are already there, but it takes
*hours* to 
have one run of imapsync over the whole account. Has anybody
got such a 
big account to sync, and does it take *that* long for you
too?

My experience with imapsync with dbmail is that it sucks.
Using a pc-client to move messages from one account to the
other is
often faster and has no failures.

Michael, I'm not sure how much bandwidth it's using, because
I'm
doing an instance-to-instance transfer of a single folder
with 23000
messages, but it is taking hours to run.
