Blocked due to Spam abuse

ebuka
Good day Morning/Afternoon/Evening Every Body, A client has been having 550 5.7.1 - Blocked due to Spam abuse. I have white-listed the email address from our outbound mail server, deleted and recreated the email account but still having the same issue. Below is the bounced back error message This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: username@gmail.com host outbound.domain.com [1.2.3.4.5.6] SMTP error from remote mail server after end of data: 550 5.7.1 - Blocked due to Spam abuse Your help will be appreciated. Thanks.

    Good Morning and a Happy new year @cPanelMichael Thanks for your response. Maybe I am not communicating the issue clearly: The mail does not get off our server in the first place, the blockage is from our own internal mail server. The error is from our outbound mail server not the receiving mail server. Thanks.
