554 email bounceback from ONE address

  • Answered
My website generates emails using the PHPMailer, sending out hundreds of emails when an event happens. There is ONE particular person's email that keeps bouncing back -- but ONLY if the email comes from my domain. If I send that person an email from my gmail or my bellsouth account, it goes through fine. Here is the error I get when I send from my domain:jmir@********.net
host mx01.gmx.com []
SMTP error from remote mail server after initial connection:
554-mail.com (mxgmxus002) Nemesis ESMTP Service not available
554-No SMTP service
554-Bad DNS PTR resource record.

Having done some research, I understand that 554 is sometimes used as a general error. My question is, do I have the ability to fix this, or is my client just doomed to not receive emails from my domain.
