Hello, I am currently facing an issue with Qmail. My email server has been listed by CBL due to the fact that sent emails show an invalid HELO greetings. According to the firstname.lastname@example.org rejection the HELO for my IP address has a valid syntax. Nevertheless, when I check the full header of an email sent from my address I find my computer IP address instead of the server's one. How do I fix this? I found many relevant threads in this and other forums, but no one worked for me. The file /var/control/me has my mail server's fully qualified domain name. I have also created a badhelo file in this directory with the value Code: # Reject spambots using our mailserver's 18.104.22.168 IP as HELO/EHLO ^11\.22\.33\.44$ # Reject spambots using our mailserver's a.mx.my.serverdomain.tdl name as HELO/EHLO ^a\.mx\.my.serverdomain\.tdl$ Where am I mistaking? I am having many troubles because of this issue, and the difficulty to get it solved. Any feedback is truly appreciated. I use Plesk 12 on Ubuntu 14.04.2 LTS. Thanks! a.
