550 no rdns entry for
Hi,
I have sendmail server, I am able to send mail to all domain but from one domain i am getting bounce mail with 550 No RDNS entry for xxx.xxx.xxx.xxx . This xxx.xxx.xxx.xxx is public ip is use for firewall outbound traffic my mail server domain public ip is different. The firewall ip is not having RDNS. how to resolve this issue. i am hoping a lot from this forum. Thanks |
It's possible the mail server you are sending to does not accept mail from a IP with no reverse. Seems uncommon but in this day and age with the amount of spam happening I think there's a high probability this is the case.

You posted earlier one domain is refusing email because the mail server you are sending from does not have a reverse lookup. I'm assuming you are running the mail server in this case you need to contact your ISP who owns the IP and ask them to put in a PTR record for that IP to you mail servers domain. This should fix it. |
