Compliance Ready: Email Sending in Eloqua deadline?

We are concerned about the following scenarios that would use a different sender domain than the bounceback:

Sending email from a campaign with Signature Settings set to Use a Signature, Send on behalf of a single user
Sending email from a campaign with Sales (a user's) Sender Email address in the Email Settings itself

In testing, the use of the sub-domain in the sender (that matches the bounceback) had the email being placed in a spam folder 50% of the time.
