I personally don't think it's worth the hassle these days. Years ago it used to be very effective, now, not so much. Some spam now retries, or they just send it multiple times regardless if the first one was accepted, both ways defeating greylisting. I rely on RBLs and spamassassin, and they are effective for me. The spam that did get through were to poker sites, and I fixed that up by adding rules to spamassassin. I think spamassassin has a db that needs daily updating, is that happening? -- http://chesterton.id.au/blog/ http://barrang.com.au/linux/ -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
