Firstly, hello to the list.

drbd is a file system replication program. However heartbeats will allow
for a redundant imapd as it can start a new server if the first one dies.

The config you would need is to use drbd to mirror the data directories
so that the mail was on both servers and then use heartbeats to detect
if imapd had died. It could then start a new server automatically.
