Email Bounces Back (Detected as Spam)

  • Answered
We have been trying to send emails today to our client @ the following address "silv[email protected]" and it keeps bouncing back to us saying:

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:

[email protected]
SMTP error from remote mail server after RCPT TO::
host []: 550 5.7.1 ... H:M12 [] Connection refused due to abuse. Please see or contact your E-mail provider.

We've never faced this before and we're facing it only with this client.

Hello Avidmojo,

Those types of errors mean that the spam prevention service that the receiver uses has an IP address listed as having a 'bad reputation'.

Spam blacklisters can sometimes be a little overzealous. Rightly or wrongly, they are refusing any emails from that IP address.

I have submitted the error message and server IP to our systems team so they can get it removed from the blacklister so you can begin to send emails to them once again. I created a ticket for you in our system, so your primary email address for the hosting account will receive a copy for tracking.

Our team is on it now and will be contacting you with resolution as soon as possible.

Best Regards,
Scott M
