Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

For my own mailserver I now have to setup PTR records for the reverse DNS.

My question is in which fields do I put what? For example my ip is 123.234.55.62 and domain mydomain.com (with mailserver mail.mydomain.com)

Name: ?
Type: PTR
Value: ?

Do I also have to update the spf record?

62    IN    PTR    mail.mydomain.com.

Further you don't have to update the SPF record since its contained in the forward lookup zone. Adding a PTR record happens in the reverse lookup zone (55.234.123.IN-ADDR.ARPA.) thus it not affects the other zone.

Reverse DNS records are configured by your service provider. This is usually the same people that assign you your static IP addresses. EasyDNS provides a tutorial that may be useful to you as well.

In the amateur world maybe but as this site is for professionals lets consider that nearly all of us handle, although not always serve, the DNS for the domains under our control, not the ISPs. –  John Gardeniers May 31 '12 at 9:27
