We manage several extremely large mail setups (10-20 million message/day). We
run exim on ext2. We run Cyrus on xfs. We are very very happy.

I have seen some problems running exim on xfs (perhaps it is a now fixed bug
in xfs). But, as for the mail storage, I think xfs can't be beat.

I would suggest keeping you exim spool and the db files (/var/spool/exim/) on
a really fast non journaled fs. (Ram disk if possible -- backed by a harddrive
of course).

I would say that I am the happiest I have ever been with 10-80 GB Cyrus
directories on xfs.

though I have no direct experience, I would wager that if you put your exim
spools on ext2, but had it deliver to maildir format on xfs you would be safe.

My 3 cents.
