    Good day,
    I have an issue with a server and 2 domains. A government site refuses to send emails to Site2 because of relay reasons.
    - Could this be a myhostname config in postfix/ It is named
    - Could this be a DNS entry in the Site2 domain. How would I go to enter a TXT Record for usernameSite2@Site1 ?

    Here's a header

    Thank You,

    It looks as if the email is sent to a wrong server. The message means that the server that responded is not the mail server of this domain. Check the dns records of the domain and make sure that they have MX records that point to the correct mail server (the mail server that accepts email for that domain).

    Thank you once again till. It had nothing to do with the installation of the server, ISPConfig, DNS, MX... It was an end user issue. I should have caught up on it faster. A good lesson learned. I guess that's what's important.

    I tried with webmail and it worked. It ended up being an error in the configuration of the customers email settings. He had forgot to put a @ in his reply email which resulted in the bad Reply To:

    email : (not [email protected]) resulted in a Reply To : [email protected]
    It was a case of bad spoofing I guess!

    Thanks again,

    Yes, if a domain is missing in an email address, then the mailserver appends his own domain name to make the email address valid.
