Ironhedz,

After reading the above article, I think you will get it to work if you do the following:

For Host ID, use the IP address 66.196.96.87. (I got the IP address by pinging smtp.att.yahoo.com.)

For Port, use 465.

For SMTP User ID, use your full e-mail address.

For Password, use your password.

IMPORTANT: For Domain use whatever follows the @ in your e-mail address... most likely yahoo.com.

You need to do this in BOTH System Wide Parameters and MClass.

After making the correct additions to your subscriber, go Port Activity and watch what happens.
