Hi dear forum and I'm new here. I heard about PROXMOX recently, literally a few days aho, and it has a mail gateway solution. So I decided to apply it to my infrastructure. Actually it works well but I have a few question that I cant find answer @ admin guide
in Administration> Queries > Deferred mail I have a lot of mails. They all have been "postponed". All mails are addressed to a different domains, but all of them have a single IP address when I nslookup it. Seems it is mail hosting provider: many mail domains under the same IP (mx.mail.gov.az is hostname).
All mails deferred with the same reason : host mx.mail.gov.az said 450.4.7.1. Helo command rejected. Host not found (ij reply to RCPT TO command)
So How to fix
