Valid PTR record?

Hi,

I am running SBS and Exchange 2003 and having trouble emailing a few domains, I am getting the "connecting ip must have valid ptr record for xxx.xx.xx.xx" error.

Can you please advise how I can resolve this?

PTR records are often controlled by your upstream ISP. You will need to work with them.

OK thanks!

How do I know what my PTR is now? And what should it be?
PTR is basically a point to the A record for the Server.

You can check your current PTR here http://www.ptrrecord.net

You need to contact your ISP and ask them to add a PTR record for your mailserver's static IP with data 'mailserverhostname'  (usually mail.domain.com or something).

So that it ends up set up as described here: http://en.wikipedia.org/wiki/Forward-confirmed_reverse_DNS
