SNDSMTPEMM - email not sending

I've started to use SndSmtpEmm and it's been working great. However there is one email still on an old domain here at work and SndSmtpEmm is failing to send an email to it. The command ends normally. I ran a trace and I see that there is an issue. I googled some of the wordings, but couldn't find a direction to take to resolve the issue. I was hoping someone here could help.

This is what I'm seeing when I do TRCTCPAPP *SMTPCLT:
rr 0 was type 1(A) this was not the requested type it was not added
The DNS is responding in the answer section with records that do not belong in the answer.
This information was supposed to be in the additional information section
It will be ignored as per RFC 2821 and corresponding DNS RFCs
A and AAAA records will be picked up later by an explicit query

It repeats the try and gets the same message as above. Then:

Valid answers: 0
no answer, no recursion, not authoritative. requested to skip referal. Query done.
No MX records found, checking CNAME for customcall.com
DNS server responded as host not found
name CNAME doesn't resolve, treat as Address Record, adding to mx with priorty 0
Resolve worked
[MX: customcall.com,priority=0]
::ffff:192.168.10.11
::ffff:192.168.10.12

I don't have any access to the email servers, but I can pass along recommendations if the issue is there and not on the Power 7. We are at v7.1. Any suggestions or insight?

Thanks,
Kurt
