Followed most of the guide... right to the end where I have discovered two problems. First one is below. Basically any address I have tried sending from gets bounced by greyfix.
Jan 7 13:46:17 spamsnake postfix/smtpd: NOQUEUE: reject: RCPT from: 450 4.7.1 <firstname.lastname@example.org>: : Recipient address rejected: Greylisted by greyfix 0.3.9, try again in 60 seconds.
Second problem. I tried using the perl script to pull the AD users for the relay_recipients. The file was created, but it didn't populate. Got any insight?
