[Linux] Postfix: Recipient address rejected Policy Rejection – Please try later

If you are managing a Lunix e-mail server and you get this error: “Recipient address rejected: Policy Rejection – Please try later.”, you can try the following steps.

Open main.cf.

# vi /etc/postfix/main.cf

And delete the following lines:

“reject_non_fqdn_recipient
reject_unknown_recipient_domain”.

Restart the postfix. This should fix the issue.
