I have my own webspace and a mail server associated with it.
Someone SENDING ME and email had the email returned to them with this message: (disguised)
Diagnostic-Code: smtp; 550 5.7.1 <me@myemail> ... [xx.xx.xx.xx](ip) Connection refused due to abuse.
I just want to confim that this error is telling the sender that their server will not connect to mine due to "abuse" on MY server... correct?
When I check the IP number it shows a SoftLayer network. My mail server is associated with my website domain has nothing to do with SoftLayer....
