A lot of RBL checkers online provide the link back to the body that is blocking it.

Try this one, past in the details and then see if there is a link to the blocking blody.

if there is no link, just google the body that has blocked it to look for contact details and contact them directly.

Here is another good site. Enter the internet IP address of your mail server and it will check blacklists.

This is saying you don't have a reverse dns entry... you need to call your internet provider (charter) and ask them: please assign me a reverse dns entry such that 66.188.39.101 reverses to (whatever your mx record is, mail,yourdomain.com)

epohl

Correct assuming mx record is set to your email server and not some third party spam filtering solution. Also try telneting on port 25 from your email server to the server that is blocking you and see what error message you get.

The odd thing is that 66.188.39.101 is not our mail server 66.188.39.99 is. So I don't know why that was showing in the log.

epohl

Do you have an edgetransport server that uses that address ? Or it is possible that depending on how your firewall is setup that is the external IP of the mailserver for outgoing.

We do have an edgetrasport server but it uses 66.188.39.99. After double checking 66.188.39.101 is not in our firewall either nor is anything pointing to it.

When trying to send mail via telnet I get this:

rcpt to:user@domain.com
550 5.7.1 unable to relay for user@domain.com
