But any RDBMS (whether MySQL, Oracle, PostgreSQL etc etc) will beat a
"read-mostly" DB for rates of change. In an ISP or volume hosting
environment, if you want customers to have changes made "live"
immediately, you can't beat having Exim tied to an RDBMS backend.
Yes, I know, there are many who do this with atomic, non-blocking,
non-racing DB exports to various file types on a timed interval basis,
and that interval can be very low, but if you've already got the hammer
that Bill mentions... ;-)
