Hi guys... I'm getting the following error on my email server... MAIL FORM user@domain.com and then the SMTP server [server-ip] said 451.4.1.8 Domain of sender address user@domain.com does not resolve. Any clue of what, it happening... Thanks in advance.
I would get that when setting up a new server. Your mail server name is unresolvable on the internet. If you are using a private domain for use on the public internet, it will try to resolve your address before receiving mail. If it can't it will fail and you will get a message like this.
