It is possible to test SMTP on an IIS server by creating an email in .txt file and then pasting it into the C:\Inetpub\mailroot\Pickup\ folder.
The text file should contain something similar to this:
to:tbill@externaldomainname.com
from:testuser@internaldomain.com
subject:This is a test.
this is a test.
Make sure there are no spaces between each colon and the text afterwards or it will end up in the badmail folder. If the email is picked up without error it will be in theC:\Inetpub\mailroot\Queue\ folder.
