Hello all,

I'm trying to understand why this is telling me host not found.
On that same server if I nslookup the ip it does resolve.

Oct 18 16:00:51 mgw postfix/smtpd[24119]: NOQUEUE: reject: RCPT from
unknown[199.5.50.180]: 450 4.7.1 <br2.vw.com>: Helo command
rejected: Host not found; from=<traderequ...@audi.com>
to=<b.m...@client.com> proto=ESMTP helo=<br2.vw.com>

There doesn't appear to be an A or MX record for "br2.vw.com".
