No. For the simple reason that the temporary files of the mail
server alone stand a good chance of killing your CF card if there
is sufficient mail traffic. Using CF for parts of the FS that are
written seldom is fine. Using it for parts that are written to quite
often is not such a splendid idea.
For a small mailserver, I'd rather go for a real disk.

CF carda are supposed to do wear-leveling internally. I wouldn't be
surprised if the dirt cheap ones skip out on that, however.

Well, the JFFS2 (Second Journaling Flash FileSystem) will do simple
wear leveling (by treating the flash device as a circular buffer and
always writing to the next block), but it requires the MTD drivers and
so only works against directly exposed flash (as tends to be found in
