Cannot delete Local (Custom) domain in virtual smtp server

joshsalmon used Ask the Experts™
I have a windows 2003 server running default virtual smtp server.  I had to mess with the settings because my ISP changed its authentication method and I haven't been able to send email every since.  In the process of trying to figure this out, I've created a custom domain that can't be deleted.  This is what I have.

dg   Local (Default)    Local (Custom)

dg is the name of the server

How can I delete the  Right Click does not give option to delete.  

I have another question that I'll make an additional post for on how to properly setup smtp server for outgoing mail using port 587.  I keep getting an error message on a bad reporting MTA of and I don't know where to change that setting.

Your help is appreciated.

I would start by uninstalling the SMTP Service,...and possibly never put it back.

Where is the real mail server?
Why do you have an internal SMTP Server to start with?


I have an IIS application that uses it to send email confirmations after an order is placed.   It's always worked until my ISP stopped allowing email on port 25.  Is there a better way to do it?

It's alright for an IIS App like this.
You should not change anything on it other than the way it connects to the upstream SMTP Server (the ISP's).
Do this by:
1. Properties of the SMTP Virtual Server (not the "Domian")
2. Select the Delivery Tab
3. Select the Outbound Connections Button
4. Set the TCP Port to 587
5. I am assuming that the ISP is using the regular SMTP,...not  SMTPS.  I do not believe you can use SMTPS with this.  But I'll admit I'm not real big on the SMTP Service in IIS.  I'm sure there are things I don't know about it.
I don't know how to remove the extra domain,...I don't have an SMTP Service on hand that I can experiment with,...the only one I have is in production , only has one Domain,...and it is not removable (it has to have at least one domain).  But uninstalling SMTP and reinstalling it should put it be to "original".
I found the answer for the extra domain name.  You have to edit the metabase.xml file to remove it and then restart IIS.

As for the Proper MTA, I've also found a partial solution for that as well.  Under System Properties, click the Computer Name tab, then click Change and then click MORE.  Part of the solution is to put in a Primary DNS suffix.  I've also got to install DNS to run on this server which it is not at the moment.


My solution was the correct answer to my question.
