Well, that's one of the problems I foresee, but also the fact that each email has a unique message ID, so I don't know if the backup server will pickup the changed messages ID's or not? I have been thinking of running a MySQL backed mail server, but have a feeling it will have a heavy impact on performance


I'm referring to the way qmail stores emails (if each email is a different file). AFAIK, this is a known problem with clustered mails servers.


Maildir is in use by almost all MTAs available on Unix/Linux or can be supported by available LDA's such as procmail/maildrop. Keeping the mail store in sync with the backup server whether by rsync or instantly by using a distributed filesystem will solve whatever problem you are thinking of in this respect.
