NB is you're doing mail archiving for regulartory reasons (SOXX etc) being
able to access the information in short timscales is critical. You have to
be able to get the to the requestor in quite a small amount of time and of
course keep 7 years of data.

This abilioty to search and retrieve quickly is where the commercial
offerings justify themselves.
