I've heard that dovecot (IMHO the best IMAP server of all) will get a 
replication feature of it's own, which should be more bandwith saving than

So bandwith is extremely expensive and you seem to be able to live with not 
extremely up-to-date data (suggested by your question about turning 
synchronisation off).

I think you'd be better of rsyncing once a day or as often as you need for 
your requirements. Should be the most bandwith saving option.

Also drbd is very sensitive to latency, so long-distance synchronization is 
not recommended anyway.
