Scot, I agree with your same assessment of using greylisting as an advance guard against spam. By itself, it is not adequate, but with SpamAssassin (and spamass-milter) waiting at the next level, these programs make an excellent team. GL is still rather new and I expect it only to get better with time. So, SA remains an important barrier and I look forward to the ver-3.0 production release. Also, agree with an earlier post that using a long delay time for GL is not useful, whereas just a few minutes does the job just as well or better. Moreover, I have also added the Sendmail plugin milter-regex which is also catching quite a bit of the viruses at the front door, thus avoiding the need to use up those heavier resources later with a scanner. I've seen my virus snags drop sharply using regex as with GL for the spam. Then Procmail filters await beyond spamassassin.....!!! Best regards, Jack L.
