I've had a requirement to do this for a long time, although I don't have
to retain the email for longer than 30 days. In the past I've used a
modified Sendmail that includes logall (e.g.,
ttp://www.freakout.de/logall.c), but that's a bit of a maintainence
issue so I switched to using the archive feature of MailScanner
(http://www.sng.ecs.soton.ac.uk/mailscanner/index.html). Using either
method, essentially at the MTA level, you'll capture a single copy of
all mail that passes through the server. A nice feature of using the
archive feature of MailScanner is that I automatically get a directory
for each days capture. So it is very easy to move those off onto tape
and very easy to search for a message received/sent on a specific day.
