For the benefit of everyone on the mailing list, I'm forwarding parts of two
emails from a exchange that took place offlist.

Your greylisting package is working great --- it's cut the spam filtering
load on my system by about 90%.  Here's the count of messages filtered by
spamassassin on my account alone for the last week or so:

    Spam count: 1008
    Spam count: 985
    Spam count: 1068
    Spam count: 987
    Spam count: 914
    Spam count: 998
    Spam count: 1137
    Spam count: 1192
    Spam count: 99
    Spam count: 105

Well, before, spamassassin was catching roughly 1000/day and around 15 were
leaking through.  Now, 900 never make it to spamassassin, it catches another
100 and 2-3 make it through.  That 900 is a godsend though: I was seeing
load averages hit 25 even 40+ once, I think.  I switched to the spamd mode,
but that only helped a little, and spamd is way too buggy, frequently going
into an infinite loop.  With greylisting, I can go back to regular
spamassassin and never notice it.
