Ive looked on their site to figure out how to fix this and i cannot find anything. I already submitted the form to be removed from the list. Which looks like it was already updated but both ip's are still returning this error.

It could be authenticated relay attack where a password has been comprimised. Change all passwords for accounts allowed authenticated relay.

Also , run a scan of public IP over at --> blacklists.

It is important to identify the issue FIRST, then apply to be removed. Keep reapplying for removal  due to multiple relisting, and you will be permanently banned.

yea thats the thing... cant figure out what the issue is. mxtoolbox is where i got the response from.

there are no auth users relay only on mynetworks.
Are you using a static IP address? I take it that this is an IP from rackspace?

You say

"relay is auth only so theres issues with an open relay"


"there are no auth users relay only on mynetworks"

So, is authentication available to relay mail using your SMTP service? If so, change all user passwords for accounts permitted to relay with authentication.

Have you run diagnostics at to make sure you are not an open relay?

If you have, then it might be that the IP was blacklisted when it was passed on to you, what do rackspace say about this?

IT Pros Agree: AI and Machine Learning Key

We’d all like to think our company’s data is well protected, but when you ask IT professionals they admit the data probably is not as safe as it could be.

It seems the IP is in the PBL which is a list maintained with co-operation from the ISP's (such as rackspace in your example) where rackspace provide a list of IP's that may be dynamic or otherwise should not be sending mail outbound.

The reason why this is flagged in spamhaug, rackspace support will know the answer to that one!

You can do one of three things:

1) Apply for the IP to be removed and see what happens, see if spamhaus remove the IP, after all, you are a genuine customer using the server to send mail on that IP, so spamhaus should remove it.

2) Contact Rackspace and get them to resolve it, as they are the ones that have provided that IP (and it will be part of a range) to spamhaus as a list of IP's that should not send mail directly.

3) Use rackspace smarthost to send mail through and then you don't have to worry about your IP reputation at all.
