I checked last week and found the following:

Handling mail for 4 domains, I get about (checking last weeks log...)
24000 delivery attempts a week.  That's just 1 every 25 seconds.  I
use greylisting.  Of the 24000, about 9600 are accepted for spam
checking.  About 7000 of those are filtered out by spamassassin as
spam.  I don't have good statistics on the remaining 2600, but I am
subscribed to lots of mailing lists, including linux-kernel, so that
could explain it alone ;-).  Just by feel I probably mark manually
about a couple dozen spams a day.  Some probably slip by for a while
in unread mailing lists.

Neither my 400 MHz PII mail server, nor my piddly DSL connection seem
to notice.  Including all traffic (not including personal websurfing,
which goes out a different connection), my connection averages about
2.4 kbps.

FWIW.
