A user on my server is signed up on a ListServ and his mail from that account is getting blocked. At first I thought the downtime between moving servers got him dropped from the list, but we have re-added him and a secondary e-mail account...the secondary account (not on my server) gets the mail just fine, but nothing from it gets to him. The user gets mail from elsewhere without issue. I have qmail-scanner, clamav, and spam-assassin running. Plesk 7.5.4 - full dedicated server (root access if I will need that to fix). So, how can I see if those messages are indeed getting blocked, why they are getting blocked, and how can I unblock them? Thanks!
