One of my servers is blocking mail from my other server

Post by midstate » Sun Mar 12, 2017 9:40 am

I am getting the following message when trying to send from one server (with MagicSpam) to another server (Also with MagicSpam). Whitelisting isn't helping. This IP is not listed on SpamRats, nor any other blacklist I can find. Regardless, we do NOT send out spam, and I'm certainly not paying to block myself. :roll:
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:

host []
SMTP error from remote mail server after RCPT TO:<[EMAIL ADDRESS REDACTED]>:
550-5.5.1 Server IP listed as abusive. See
550- for more information.
550 Protection provided by MagicSpam 2.1-5.3

Please advise on how to fix this.

Thank you.
