We ran some benchmarks a while back between EXT3, XFS, JFS, and ReiserFS with
both qmail and mysql. While MySQL didn't care much, qmail was able to deliver
between 10,000 and 20,000 messages per minute more on XFS than either other
option. Also,

easily corrupted. xfs seems the best.

We have 4GB's of RAM on the I-RAM which should be more than enough for the
qmail queue and log files. I'll check out JFS. Thanks
