I'm pulling hair out trying to get MP to relay through the godaddy mail servers... I've read half a dozen different blog posts on how to set it up and I've got NOTHING :( ... 

The Setup: MojoPortal, built from source, with a couple of small modules that I've created, no changes to the MP source at all.
The Platform: Windows Azure

I've tried targeting smtpout/smtp/relay-host.secureserver.net with and without authentication, on ports 25, 80, and 3535 (as recommended by GoDaddy support)

I'm getting no errors in the MP logs, but I'm also getting no indication of anything being relayed by the GD mail servers (you can see how many relays have been processed in the GD control panels.. I'm still at 100% of available relays per month)

I've set up other CMS to use the GD mail servers (DNN, Orchard, etc) with no problems. Orchard was tested just last week in fact...

Can anyone tell me about their confirmed working setup for using GD mail ?? Azure hosting prefered, but knowing if I need to blame MS/Azure or not would be helpful too :)

I was trying to test by using the "resend verification email" feature on a user account I created with one of my alternate emails, but I think that because the email for that account was manually entered it considered the address already verified (grayed checkbox) and that the request to resend was being silently ignored by MP. I got it working by turning off per-site email configuration (which may or may not have been part of the problem.. I need to retest that as I will need that capability when I add more sites)

For godaddy mail servers I got it working using

smtpout.secureserver.net:80 RequiresAuth=true SSL=false

ports 25 and 3535 should were also tested as working with a local test app I created to try all the possible combinations I had seen in various blog/forum posts.
