Subject: [iMS] MX Lookup error
Hi
Howie,
Our IMS is
getting an MX lookup error for a particular domain from 2 of our DNS servers.
When I do an MX lookup on the particular domain using NSLOOKUP, an
MX record comes up. Our office mail server (which is not IMS) has no
problem looking up the MX record and sending mail to the domain in question.
Do you have any idea as to what could cause this? I have noticed that
the MX record has a different format than our MX record. Could the
difference have something to do with the problem?
I have included a
sample of what I see for the recipients domain when I do the lookup through
NSLOOKUP (the domain names have been changed to protect the innocent) and what
I see when I look up bigdough.com.
domain.com MX preference = 10, mail exchanger =
mail.domain.net
domain.com MX preference = 20, mail exchanger =
mailhost.otherdomain.com
mailhost.otherdomain.com
internet address = 123.456.5.10
mailhost.otherdomain.com
internet address = 123.456.5.11
mailhost.otherdomain.com
internet address = 123.456.5.12
mailhost.otherdomain.com
internet address = 123.456.5.13
bigdough.com MX preference =
20, mail exchanger = mail2.bigdough.com
bigdough.com MX
preference = 10, mail exchanger =
mail1.bigdough.com
mail2.bigdough.com
internet address =
192.168.100.20
mail1.bigdough.com internet
address = 192.168.1.9
