Yea! reverse dns has been set up, and suddenly RoadRunner is giving me
list email again. (Thanks jp)
If I understand jhriv's explanation, the rfc2821 explicitly says that:
"SMTP .. servers MUST NOT refuse to accept a message [on the basis of
lacking rDNS verification]"
I was wondering whether I should gripe to RoadRunner?
Many mail servers are configured to not accept mail if the sender
(server) does not have rDNS. This sometimes causes the server to be
placed on a blacklist. We can thank spammers for this and I don't think
it's a bad policy. Every person sending mail, and every server, should
provide all the identification it can.
Our mail servers are configured to tag senders that can't be identified
as potential spammers. The mail is not dropped because of a lack of rDNS
unless the recipient has configured their domain to do so.
I consider a mail server without rDNS broken.
