How to get CDONTS to work on a server that has a 3rd party SMTP server running on same server

How to get CDONTS to work on a server that has a 3rd party SMTP server running on same server by Mike Lopilato

Here is the problem Mike was having

I read your article "Using SMTP(CDONTS) to send email  from an ASP Page" 
    
The problem that I am having is this---I'm running NT4, SP4, Option Pack 4 and Ipswitch's IMail
Server on the samebox.   IMail uses port 25 for SMTP.  I can't get CDONTS.NewMail to send
the email.

How do you get CDONTS to work on a server that has a 3rd party SMTP server running on it?
    

Here is the solution

Set the 'Outgoing Connections' port to 25,
The 'Smart Host' using the IP address of the IMail server, and the 'FQDN' as the FQDN for the IMail Server.


Thanks Mike for sharing your solution!
