I have gotten a couple errors lately from email sent from a virtual server.
Sender: Please tell postmaster at your system: Could not
find PTR record for your mail host <ip address of virtual server>
This is pretty new, and comes after adding second server.
First server: use DNS service of godaddy to point domain Domain.com and server web1.Domain.com to my ip address. (yes, real server has different one...owned by hosting company). I then added another server billing.Domain.com. Problem showed up after this, but not sure that's related. Could be I'm just sending mail to new locations that would have always flipped.
on mail server (web1.Domain.com) i get
[root@web1 ~]# dig -x <ip address of my server>
; <<>> DiG 9.3.6-P1-RedHat-9.3.6-4.P1.el5_4.2 <<>> -x <ip address of my server>

I am not running named on this server (although I haven't shut it down on billing.domain.com.
How do i get a PTR record to show?
