There's a distributed filesystem especially tailored for /var/mail,
its called IMAP.
That doesn't mirror stuff, Paul.
I get the impression the poster wants more than just mirrors/backups of
/var/mail, for which there are various solutions (rsync or other
$FAVOURITE_BACKUP_SOFTWARE) but ability to easily access redundant
email-stores.
Step 1 toward that goal would be, imho, to use IMAP as the access
protocol.
Step 2 after that would be to investigate HA/redundant IMAP server
/implementations/.
E-mail-store redundancy through IMAP gets you into "Something a lot of
people like to have, something which various vendors/projects offer
solutions for, something various other sites may have experience of"
land. (E.g. There are IMAP proxies that might be able to help. There may
be IMAP server implementations with redundancy features).
Email-store redundancy through distributed-replicated FS gets you into
an unenviably solitary position, imho.
My 0.0156 Euro worth anyway ;).
