I am having problems sendings Emails to some domains. I believe it has to do with my reverse lookup. In DNS I have an A record for mail.xxx.com and a MX record setup. I have a reverse pointer record set up for mail also and it works correctly in nslookup.
When mail goes out however, it received as
MAIL_SERVER.xxx.com
(firewall.xxx.com [207.x.x.x])
the IP address is the address of my firewall and not the mail server. Reverse lookup works for the firewall, but of course comes back with the firewall's address not the mail server. How do I correct this?
