So we have our server on the domainname.co.uk and reverse dns resolves to mail.domainname.co.uk which is all fine and dandy.
But what about then other TLDs sends from the server too?
Lets say for example that peter@domainname.se or christine@domainname.dk sends from the server and now email servers around the world will so a reverse lookup and find out that @domainname.dk reverse DNS does not match SMTP Banner.
So do we need to setup corresponding PTR records for the other TLD's we are sending from to avoid that our server's mails get tagged/marked as spam?
Thanks in advance for help.
Kind regards
PTR records for other TLD than origin server TLD name?

Re: PTR records for other TLD than origin server TLD name?
Hi,
Reverse DNS is done on the IP address, not the domain name. So as long as the reverse IP lookup works, and returns a domain that then resolves to the same IP address it will be ok. So you are ok to send as any email address once you have a PTR for the IP address you are sending on. Just make sure you have SPF records for the domains you do send from, since they are checked.
