Smtp and pop for user



  • Hi everyone, I have setup pfsense as a firewall at work network.We all use exchange as our mailing platform. I have one user that would like to add a private pop account to his email accounts. When I do the testing, pop works, but not smtp, in other work user can receive his private emails but not send. How do I enable just this single user to send via his personal email account?Any help would be greatly appreciated.

    It's probably the ISP blocking outbound port TCP/25.  Try TCP/587 with STARTTLS + SMTP AUTH.

    Do you explicitly block outbound SMTP or any ports outbound in general?

    If you do, set a static IP for his machine (or reserve one in DHCP) and create an allow rule with source IP as the machine IP, destination port as SMTP.

    If you do not block any outbound traffic, then this issue is probably related to your service provider (some of them will block outbound SMTP traffic unless you route your mail through their open relays).
