I have a dedicated server at OVH.
For several days I've noticed I'm in a spam list (spamcannibal).
The reason I said was for generic PTR. I've changed and I have commanded to remove from the list.
I've been reading about the steps to configure the dns well but I did not clarify.
I have 3 domains hosted on my server and send emails 3.
if I type host [my ip] servidor.mydomain.com me back and if I type host [servidor.mydomain.com] return my ip
Is this correct? mydomain.com is one of the three that I have hosted
