Exchange 2007 - message header config question; kinda urgent

[travisGa...@hotmail.com]

Hi all

Having a serious problem here.
Have an Exchange 2007 Server at IP 68.162.218.212 on a machine which is
also the domain server with internal name "mail.zenRx.com"
Our external name is: zenRx.org
We hardly ever sent manual eMails from zenRx.org, approx 10 per month.

While we were installing the Domain/AC, there is one place... when you enter
the name of the domain server as "zenRx", it labels it as "zenRx.com".
So we are stuck with this ".com" thing.

Sent an eMail from wish...@zenRx.org to my personal eMails
sy2...@yahoo.com and to my hotmail accounts.
In both cases, they ended up in junk mail area. Don't know much about the
default most common filtering criteria, but I think I can see the problem
with the header.
zenRx.com vs zenRx.org (definitely) ..... is it also 127.0.0.0 vs
68.162.218.212?

Is there anything I can do, since I cannot change the mail server's name
from mail.zenRx.com to mail.zenRx.org even though the entire setup is legit
zenRx.org.
The question: How can I prevent the eMails from being treated as junk/spam
mail.

The problem is that when I send and eMail this is the header it goes out
with:

Well, the PTR record for 68.162.218.212 identifies the server as
static-68-162-218-212.BOS.east.verizon.net -- so that might count
agains you.

And the IP address assigned to mail.zenrx.com is 82.98.86.161. The PTR
record for that IP address identifies the machine as
www161.sedoparking.com. That, too, can be a problem.

Your real problem, however, is "X-YahooFilteredBulk: 68.162.218.212".

Yahoo (and the SORBS (for sending email to their spam traps) and
SpamCannibal (listed as a spammer) DNSBLs) have you pegged as a bulk
mailer (a nice way of saying 'spammer').

Now, to fix the name your server sends in the EHLO\HELO command, alter
the FQDN on the Send Connector's property page. Make sure you have an
"A" record for the name in your internal DNS and external DNS. And get
Verizon to change your IP address's PTR record to reflect the FQDN
too.

Thank Rich. I will deal with Verizon tomorrow morning. I am sure we can
solve that problem.

But "mail.zenrx.com" is just the machine name and it is "internal".
Why can't I shield that name, and have a name that reflects my valid domain
name zenRx.org?
Is there any way? I have full control of the DNS MX Records.

zenRx.org is a domain name, not a FQDN. In many cases (perhaps not
yours, or perhaps not yours right now) the domain name's A record is
associated with the company's we page. That IP address may not even be
in your network but in some other company's web farm.

Your server should be using a name such as mail.zenRx.org in the
HELO\EHLO data.

>Is there any way? I have full control of the DNS MX Records.

Sure. Use, for example, mail.zenRx.org, as the FQDN and put that A
record into your internal and external DNS. Modify your MX to use that
A record and update the PTR record for the IP address to agree with
that name.
