Hello,
In addition to what has already been mentioned, you might also have to define your hostname in
/etc/hostnameand make sure that the hostname for127.0.0.1in/etc/hostsmatches that too.Best,

Hi @aecsp2000,
I’ll recommend checking the error log to see the exact reason as to why you are receiving this message. The error log should be located in the ```/var/log/` folder somewhere. The file is usually called /var/log/maillog, /var/log/mail.err or /var/log/mail.
Additionally, you can try to reconfigure Postfix with the following command
Just let me know which options are you selecting.
