I'm having trouble configuring my E-Mail settings in OBIEE 12c. My 11g system works fine. Here are the pictures of the email configurations in both systems. As you can see, they are identical.


When I run an Agent in 12c, I get this error:

Notice that it isn't saying that it can't authenticate the credentials. It is failing to open a connection, and doesn't even get as far as the credential authentication.
I tried the suggestion in this doc, even though it was related to 11g. It removed the credentials properly, and I replaced them on the email configuration page and tried again. No go.

But again, I didn't think it was the credentials anyway.
What am I missing?
