It says the following:
APEWS.ORG Databasetest
Oooops xxxx is currently listed in APEWS :-(

Unallocated CIDR, no traffic until allocated,
or allocated to bad reputation provider
or allocated but dynamic / generically named IPs,
or bogons, see,
or orphaned IP / CIDR in routing table

I've also noticed I have received a few bouncebacks with the following messages:

#5.5.0 smtp;550 Local CT IP Reputation Policy (Reject) ->

#5.7.1 smtp;554 5.7.1 ACL dns_rbl; Client host [] blocked using Please visit for more information on why this message could not be delivered>

#5.5.0 smtp;554 Sorry, message looks like spam or phish to me (OP)

Have I been given a dodgy IP address?

If you've changed external IP Addresses then yes it looks like you have been given an address that has been previous black listed.  Get in touch with your ISP and have them resolve it / delist you.

You can do this yourself if needed but I would complain to them as its poor service and should have been checked.

Use to check your IP and domain name against other blacklists.

It sounds like you are sending directly out to the internet.

What are you using for anti-spam / anti-virus filtering?

If you have a hosted solution such as Microsoft's Exchange Online Protection I would recommend doing outbound filtering through them as well. Solves all my blacklisting problems. :)


Ok so I have checked mxtoolbox and asked the provider and they say we are not any blacklists.

Any other suggestions?

What does "are sending directly out to the internet" mean?
Using ORF for Spam.

That you are not using any kind of outbound filtering. Your Send Connector is not configured to use a smart host.
