Question : Mail Server & Reverse DNS

When I send out e-mail from my mail server, the real word receives the address as, for example, 192.168.0.4; however, when you do a reverse DNS on my mail server's address (e.g., 192.168.0.4), the address returned is that of my authoritative DNS server, for example, 192.168.0.9.  In the end, some people reject my e-mails because the reverse DNS does not match that of the sending mail server address… does anyone know anything about this, or have any advice, so that I can eliminate this problem?

Thanks!

Answer : Mail Server & Reverse DNS

well from this statement "reverse DNS on my mail server's address (e.g., 192.168.0.4), the address returned is that of my authoritative DNS server" leads me to believe that you have incorrect reverse dns records.  when anyone does a reverse lookup of mail.yourdomain.com they should actually get the public IP address of your mail server, not your public DNS server's IP address.

run a check of your dns records on www.dnsreport.com and see what you get.  If there are errors or warnings contact your ISP since they manage your public DNS and its their job to get it right.
