You see the following error in your mail log:
Jul 18 12:14:33 mail postfix/smtp[1911]: 8C7372CF60: to=<[email protected]>, relay=none, delay=0, status=bounced (mail for example.com loops back to myself)
Please add example.com to the mydestination line in /etc/postfix/main.cf and restart Postfix:
service postfix restart
It worked!
I have same error but it already has my domail in /etc/postfix/main.cf
mydestination = holmtek-research-ltd.uk, localhost, localhost.localdomain
Works as charm! Thank you :)
So this means I should be adding gmail.com, hotmail.com, outlook.com, yahoo.com, icloud.com, whatever_other_domain_imaginable.com to my configuration ?????
No, this does not mean that. You just add your own domain name there, not recipient domains.
https://www.postfix.org/BASIC_CONFIGURATION_README.html in order to avoid mail delivery loops, you must list all hostnames of the machine, including $myhostname, and localhost.$mydomain.
