We currently send mail directly through DNS lookup on our exchange box.
We get blocked by like AOL and hotmail for not having a PTR record from what I can see.
if I check the PTR for our public IP it comes up as
With the XXX being the IP.
Does this need to be the domain that we are sending email from?
I've tried contacting BT support but they didnt even know what a PTR record is.
Our actual domain we send from is hosted elsewhere as we use them for POP mail.
Thanks in advance.
