This is not a good argument for replacing sendmail, considering the fact
that 100,000 messages an hour is sufficient to handle the needs of a
userbase of 100,000 users or more.
BEST has two incoming mail servers, running sendmail, to support it's
30,000+ users and the mail rate is only 150 messages a minute (per server)
at peak.
BEST's outgoing mailing lists machine is our busiest mail box. The
outgoing mail rate, doing the mailing lists for all best users (a few
thousand mailing lists) is, at peak, around 1000 messages a minute at
peak (around 60,000 an hour).
Sendmail is not the lightest weight program in the world, but it is the
most mature and it is relatively easy to configure it to resist all sorts
of potential blowups, attacks, or whatnot.
I think it's a bad idea to replace it in the base distribution and an
even worse idea to put both sendmail and something else in the base
distribution.
This new mail program thingy should be a port. I would like to point out
that there is nothing wrong with ports... hell, even 'less' is a port!
