Hello remaining lurkers,
This is not about SIMS, but it does involve CGP, so perhaps it is of
peripheral ontopicness. Nonetheless, the question involves a mail
connection rejection due to "DNS failure."
The connection is to afterhoursconsulting.org, whose mail is handled
by mail.rduonline.com, which is running CGP 4.0.6. I picked up on
some forum the possibility that this is a bug in 4.0.6, but I
wouldn't know.
As a sanity test, I can telnet connect to mail.rduonline.com as my
mail server (HELO mx.4pi.com). However, when I telnet connect to same
as the problem mail server (HELO mail.tmug.org), I get a DNS server
failure immediately. This is initially a 250, but ultimately becomes
a 472. Although I understand this to be a temp failure, it is really
a permanent failure.
So, I look to how I have DNS set up for both mail servers. mx.4pi.com
has a unique A record, MX record, and PTR. Likewise for
mail.tmug.org; however, I see 2 PTR records, one for mail.tmug.org,
and one for tmug.org. Not sure how that happened, I need to talk to
my DNS admin about that.
Questions: is this minor difference what is causing the DNS Server
failure with CGP? If so, should I change the DNS, or is this indeed a
CGP bug?
