How to change Helo Address?

rated 0 times [ 23] [ 0] / answers: 1 / hits: 35794 / 2 Years ago, wed, november 2, 2022, 6:58:37

Right now my Helo Address = localhost (helo=localhost). Is it better to set this to my server's domain name? If so, how do I change it? I'm running Ubuntu 12.04 and Postfix. Thanks.

You can change it in postfix configuration file /etc/postfix/main.cf.

The helo line is controlled by the smtpd_banner parameter. It probably references the myhostname option. Put your server name there instead of localhost:

myhostname = server.example.com

smtpd_banner = $myhostname

and restart postfix with sudo postfix reload.
