We are having Exchange 2007 Message Delay Problems

I have looked everywhere and am unable to come up with a resolution.  I have an exchange  2007 server setup on Windows Server 08.  I have created the most simple senerio in order to troubleshoot this.  Basically there is no edge server and it is just a hub transport.  The send connector is a default "*" with the FQDN set at our domain.  I used the shell manager to add this FQDN again.  There are about three receipients out of 100 that we get back a delay message and a couple of days later a failure to deliver.  PTR records seem correct.  When I telnet to the mail server I am still seeing the local domain server name but I have read up on it and I don;t think this is the problem.  I have message tracking and logging enabled but do not see anything funky.  Here is the header I get when I send to gmail.

Does anyone see anything wrong or know a way to troubleshoot.  I have KB articles one after another to no avail.  Any suggestions would help.  Thanks

Are the users that have the delay on the same domain?  Probably not?

This sound more like a DNS issue. Make sure you Exchange server itself is using the internal AD DNS server and there are no forwarder.

Mrmin: The senders are on the same domain, Recipients are not.

MickeyFan: Sorry, but could you elaborate, this comapny only has this one server running everything.  And all internal mail and connections are working correctly.  How do I check if Exchange is using the AD DNS.  Thanks

Also I have checked with the recipients and they claim to have no other issues.  One is a Blackberry account tmo.blackberry.net

Perhaps your MX lookup on the Domain Name registrar is not right.

If that was the case I would not get any mail, would I?

Run IPconfig /all

Make sure the DNS is point to your AD Server.

Make sure you are not having bandwidth problems as well.

You can also try and clear the cache on your DNS Server as well. CMD -> dns /clearcache.

We may be getting somewhere.  Running IP config i am seeing:

DNS Servers ..... ::1
                            127.0.0.1

The Exchange server is also the AD server.  So I am not sure if this is supposed to be what it looks like.

That IP address is for your loopback.  This is normal.  Logon to the Exchange server.  Open CMD.  Type:  ping google.com

Weird, on DNSStuff the REV dns was correct.  This is most likely my problem.

Not until you test it again.

Sorry, I mean that mxtool found bad rdns.  I just checked my domain registrar and I think I may have found my problem.  Looks like my mx record is for a different domain that I own.  I feel pretty stupid
