Adding a second A record

I'm trying to get my DNS in order for maximum email delivery. One of the problems I'm having is that my mail server hostname differs in IP from the domain I am trying to send from.

So I added a second A record in mail server's DNS for the domain's IP. I pass DNSREPORT.com now hands down, but I received this email after running UPCP.

IMPORTANT: Do not ignore this email.
The hostname (host.name.com) resolves to 12.34.567.890. It should resolve to 12.34.567.889. Please be sure to correct /etc/hosts as well as the 'A' entry in zone file for the domain.

Some are all of these problems can be caused by
/etc/resolv.conf being setup incorrectly. Please check this file if you
believe everything else is correct.

I sure this is a common issue, but can't find anything in the forums when searching. Is it safe to ignore that email?

 

I have two A records.

I have it pointing to the IP of the hostname and and a second A record pointing to the domain I send high volume email from. IS it safe to leave that second record in there, is my question?

 

Here's my zone.

Here is the zone 'A' entires for my mail server:

;; ANSWER SECTION:

host.server.com. 14400 IN A 12.34.185.228
host.server.com. 14400 IN A 12.34.185.233



IP: 12.34.185.228 Is the IP of mail server

IP: 12.34.185.233 is the IP of the domain I send high volume mails from.


Thanks for your help!

 

Thanks.

Thank you for the input, I will make the adjustment.
