Trouble with backscatter

[NetsSource]

Hi All

We moved a customer to a new server with clean IP's. Shortly afterwards, one the IP's was blacklisted at backscatterer.org:

This IP IS CURRENTLY LISTED in our Database.
Please note that this listing does NOT mean you are a spammer, it means your mailsystem is either poorly configured or it is using abusive techniques.
This kind of abuse is known as BACKSCATTER (Misdirected Bounces or Misdirected Autoresponders or Sender Callouts). Click the links above to get clue how and why to stop that kind of abuse.

I checked Sender Callouts and it's disabled. I haven't checked SMTP logs yet. Is there any other settings I should check that might have gotten this IP blacklisted? Thanks.

Hi @NetsSource


The advice provided in this documentation is extremely useful How to Keep your Email Out of the Spam Folder - cPanel Knowledge Base - cPanel Documentation

As far as misdirected bounces or autoresponders you might check the thread here: Definitive way to stop misdirected bounces/backscatter the insight is pretty useful information and may be helpful in resolving the issue.
