Hello All,
I'm attempting to configure Postfix 3.3 on a freshly-installed Ubuntu 18.04 LTS
system. The system will do nothing more than relay mail (for status and
summary e-mails) to my main mail server. The same configuration works using
Postfix 3.1. What am I missing? Thank you for your time and assistance.
