IMAP Synchronization

I hate it. IMAP Synchronization, that is. In an effort to migrate users from one *shudder* Exchange provider to another (after getting shot down for proposing first Zimbra, then standard mail server stuff, then Openchange), I have been going through all of the available IMAP sync software that I could find. mbsync () – We use this for IMAP backup, so I figured it would be a good idea to try it for syncing between two IMAP servers.
