spamc/spamd is highly recommended.

I think the problem is exim's handling moreso than the others, so your
suggesting may be sane.  I trimmed my max messages accepted from ~100 to
~50.  I've got exim running queue every five minutes, which I think I'll
cut to something like 2-3:

    /etc/exim/exim.conf: smtp_accept_queue_per_connection = 50

...and the appropriate mod in /etc/init.d/exim.

If I understand properly, this should cause exim to attempt fewer
simultaneous delivers, and spread deliveries out over several minutes.
