I send a mail to a specific email and I recive the following error:
"SMTP error from remote mailer after end of data:"
"550 Error: Message content rejected"
THIS ONLY happens if I send the mail from a specific sender example: (firstname.lastname@example.org)
IF I send the same mail from another sender email@example.com
The message arrives fine.....
So I don't know what could be wrong. The body is the same ONLY the sender is different.
Anybody can help me?
please send your anser ALSO to firstname.lastname@example.org
so I can read as fast as possible because I must have the solution to this problem as soon as possible.
