I have some co-workers that are writing an email parser (not sure of

being "fast" enough to parse that many emails.

I have no definitive experience with something on this scale but I am
sure someone on the Perl group does.
5000 emails per day, that's 17 seconds per message. You can do a lot
of parsing in 17 seconds, even in Perl.

That is what I was thinking, even if it was an 8 hour business day that
is still 5 seconds per message. Granted I don't know if that is a
steady influx or a deluge.

I'm doing email filtering on a number of servers with roughly the same
amount of traffic, and even on old systems (P3-class) this runs
quite smoothly, even though there's a number of scripts and
external programs involved which pipe the mail content back and
forth. If your co-workers are still worried (maybe they expect
traffic to grow fast) they could build a threaded solution, which
would rid them of the most expensive part, which will be loading
of configuration items and the compilation and startup of the
script itself.
