Try adding the IP address of the web server in the Relay Restrictions of its
SMTP server. In other words,
Say the IIS Server that sends the e-mail has an IP address of
192.168.168.25.
1. Go to the IIS Admin MMC ~ the SMTP Server properties ~ Access
~ Relay
2. Choose "Only the list below" and add 19.168.168.25 to the list
3. Leave bottom checkbox checked that talks about authenticated users
4. Hit OK and mail should immediately be delivered
Hope this helps, this just worked for me and I have been battling the same
scenario you described for the past 6 days.
