Subject: Slightly OT: Greylisting success or failure stories?
I looked for any discussion lists about greylisting and haven't found any, so I thought I might try asking here.
I'm considering adding greylisting to my postfix configuration, and some of the articles I have been reading about greylisting show that there can be any of several situations in which greylisting would not be a viable solution.
In particular they mention issues with how some MTAs break something in the RFC that makes greylisting work, and how receiving mail from a site which uses multiple relay hosts (each with a different address) can also cause mail to not be delivered.
So I thought I would ask on the list to see if anyone has done much with greylisting and found it to be good or bad.
I do also use the DNSBL lists, and some of my accounts also use TMDA. What I am hoping for is that with greylisting, I can further reduce the amount of spam mail traffic.
Thanks. David
I have been using milter-greylist with Sendmail and I am *incredibly* impressed. Between SpamAssassin, spamass-milter, DCC, Pyzor, Razor, ClamAV, clamav-milter, and milter-greylist, I literally receive no spam in my Inbox. None.
About once every two to three weeks I get a really low-scoring spam that makes it into my spam folder. The rest are all rejected at the mail server. Last time I checked the logs my mail server (used only by my family) was rejecting something like 1600 spams per day.
I absolutely love it.
