If they adapt to greylisting and start following relevant RFCs, we've succeeded in making spamming more expensive. I don't see that happening much, though. The spam that reaches content filtering here has managed to get itself into the queue on real mail servers which for some reason allows them. On the 'spamd looks like an open relay' issue, it would make sense to use a relay checker which actually checks for mail received, not just the status codes. On the other hand I actually like that part of spamd the way it is. Spammers who apparently think every IP address in our range is an open relay occasionally swell our greylists quite a bit. None of it ever gets delivered, of course, but we see the attempts quite often these days. -- Peter N. M.
