Masquerade Domain

[silentsam33]

I am currently running Exchange 2000 SP3 on a Windows 2000 server SP3. I would like to hide my mail servers FQDN from headers, do I set a masquerade domain name and should my masquerade Domain name be the same as my mail servers MX record. I believe this is what needs to be done, but just wish to check first. We were having a problem mailing to one domain and it turned out they were using reverse DNS lookups and we did not have reverse PTR setup. After talking to our ISP to update our records they suggested hiding the mail server FQDN and use our MX record name.

I put in my MX record (mail.domain.com) in the masquerade Domain field and restarted the SMTP virtual server, but the mail server FQDN remains in the headers. Just below the Masquerade Domain field there is the FQDN field which lists my server full name. Do I have to replace the FQDN field with my MX record to see a change in the mail headers? I am trying to hide my mail servers actual name in the headers and replace it with my MX record.

Thank-you for any suggestions.

I am going through the exact same thing as well, have you had any success yet? I am running 2 exchange 2k boxes at 2 different sites, and one works correctly and one does not. the headers from one have the mx record name, not fqdn and the other shows the servername.mydomain.local in the headers!! I want it to say mail@mydomain.com like the other says mail2@mydomain.com. I know this can be done, however I don't recall doing anything different setting up the second server and it works correctly.

I also had the PTR issue and had that resolved today, hopefully I'll be able to test this successfully after the dns change replicates out. Anyway, post up if you've figured this one out yet and I'll do the same if I find a fix.

silentsam,
I've had some success with this, I was able to get the header to display the mailserver name that I wanted by creating a host record on my local dns server in the external.com forward lookup zone and also an MX record in there pointing to my mailservers internal IP address. Afterdoing this I was able to change the FQDN field you spoke of to mail1.mydomain.com and it took it successfully authenticated the name in DNS. This took care of the servername, however, message ID's are still going out with the myservername.mydomain.local, haven't found a fix for that yet.

Thanks for the update. I had wondered about the DNS resolving of the FQDN to the MX record. I havn't had time to try anything new to resolve this issue.
You mentioned that 1 server displays the external name and the other the internal in the headers. Is there anything different between them such as Exchange roles (i.e. bridgehead server) ?

 

[SmokinRR]

Well, being that they are at different sites in the same organization in a similar configuration (each behind a single firewall) they are both bridgehead servers for their site. I'm actually right now going through the settings and there is nothing that I can see that is different. I didn't even have to change the fqdn are on the working server, and the masquerade field is blank! Everything just works the right way on that one and I'm drawing a total blank as to why I have to jump through hoops to get my other server to look the same from outside. I just can't explain it. BTW, the one that is working is actually the second exchange server added to the organization if that helps.

I've been using this thread as well, this is where I got the internal DNS stuff to try.
