Hi!
I was looking for a qmail solution for greylisting. I noticed qgreylist on RH9 SRPMS, and tried it for a couple of days. Very easy to get it running, and worked fine. However, i wanted something more robust, SQL based.
I got the greylist patch at shupp.org, integrated it with scott's qmail SRPM, altered it to eliminate a couple of very simple patch rejects (it's the last patch applied on the SPEC file), and also tweaked logging.
It's now working great on two MX's. I block 99% of SPAM before it even reaches Spamassassin. No legit mail blocked. I should have done it earlier!
Scott, i highly recommend this.. maybe a qmail RPM with greylisting and another without.
I see one problem though.. the MySQL access config is hardcoded on the patch. It needs to be set prior to compilation. Maybe the patch could be altered in order to read this from an external file. And maybe even the greylisting could be set on/off dinamically (presence or absence of /var/qmail/control/greylist?)
I leave the suggestion!
Best regards
