Hello, I'm running ISPConfig 3.1.1p1 and have Greylisting enabled on 1 mailbox to test it out, but it doesn't seem to work. Also in the maillog I don't see mails getting greylisted. What could be the problem? Greetings.
Did you install postgrey first and ran an ispconfig update with reconfigure services = yes after you installed postgrey?
I re-installed and re-configured postgrey and it seems to be working now: Nov 24 10:21:25 mailserver postfix/smtpd[31335]: NOQUEUE: reject: RCPT from spffrpar5.DOMAIN.com[***.*.***.**]: 450 4.2.0 <[email protected]>: Recipient address rejected: Greylisted for 60 seconds; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<SPFFRPAR5.DOMAIN.com>
