Are you familiar with the following?

R$1<@$2>$3    $#error $@ USAGE $: "aaaaaaaaaaah"

Well, I am. Yes, very familiar. And I still like sendmail. Enough said.

There's a faint possibility that you might want to see what anti-spam hacks I've added to version 8.8.8+. Yes, I know that this is almost paleolithic in comparision to today's versions. Still it was a nice setup then. The new stuff is good for all of us, but there goes my effort :-).

Recently I've played with milter, the sendmail on-the-fly filter system - and I still like the beast (must be congenital, then).
