Apparently, name servers at greenmountainaccess.net are also hosting NS
records for you. Are you sure they have it right? If I'm trying to
resolve "mail.bfafairfax.com" from the outside world, I'm probably
hitting one of their servers first (as is all your incoming Internet
mail) whereas you are querying your internal DNS first. If Green
Mountain Access has an erroneous MX record, that would screw things up
even if your internal record were correct. Maybe you should have them
check their records next.

I do our DNS. :(
Perhaps therein lies the trouble, although I've quadruple check the
records and they seem to be OK.

Who Does your DNS?
I am no expert but it looks like your mail exchange in your mx record

Can any of you Groupwise administrators help with a problem that I'm
Our Groupwise 6.5 sp2 server appears to be responding to other email
servers with the wrong hostname. Because of this, the surfglobal.net
email server rejects all mail from our domain. It thinks that it is
The error report under the properties of the rejected email gives the
following error message:
504 <mail>: Helo command rejected: need fully-qualified hostname
A report on our domain from www.dnsreport.com gives the following
WARNING: One or more of your mailservers is claiming to be a host
than what it really is (the SMTP greeting should be a 3-digit code,
followed by a space or a dash, then the host name). This probably
cause any harm, but is a technical violation of RFC821 4.3 (and
4.3.1). Note that the hostname given in the SMTP greeting should have
A record pointing back to the same server.
mail.bfafairfax.com claims to be invalid hostname 'SMTP': 220 SMTP
Our server name is mail.bfafairfax.com. When I telnet in to
mail.bfafairfax.com on port 25, it responds:
220 mail <some Groupwise stuff> ready.
Should it respond:
220 mail.bfafairfax.com <Groupwise stuff> ready
instead of just mail?
My host and hostname files on the Groupwise server reflect
mail.bfafairfax.com and its private IP address. My gwia.cfg file
Our Groupwise server sits in the DMZ behind our firewall. It has a
private IP which has a 1-to-1 NAT to the public IP.
I just can't figure out what is happening.
Thanks in advance for any help you might be able to offer.
