[Dovecot] Same filenames on different servers?

Use Heartbeat and DRBD for replication - all mail is synched between the 
servers.

If first crashes, heartbeat runs "second" as new server for the users.


As dovecot on "second" is only started if "first" is down, there are no 
issues about inconsistencies.


best regards,
