I encountered a problem with iRedMail running postfix and it not being able to receive email from certain external mail servers.

The error I received from my email client (Thunderbird) said the following:

----- Transcript of session follows -----
... while talking to mx1.example.com.:
>>> DATA
<<< 553 5.7.1 <user1@example.com>: Sender address rejected: not logged in
550 5.1.1 <user2@example.net>... User unknown
<<< 554 5.5.1 Error: no valid recipients

And the log file on the mail server stated:

• The problem turned out that I needed to edit the postfix main.cf file:
  

  vi /usr/local/etc/postfix/main.cf
  

  • And remove remove the reject_sender_login_mismatch
    

    # Removed reject_sender_login_mismatch option
    smtpd_sender_restrictions = reject_unknown_sender_domain, reject_non_fqdn_sender
    , reject_unlisted_sender, permit_mynetworks, permit_sasl_authenticated
