One more edit: at least *in theory* using authenticated SMTP should allow you to connect from anywhere and bypass the RBL. If your corporate email administrator configured things properly...

I *am* using authentication for accessing the server. I have the correct SMTP settings. I just can't figure out why/where I am being blocked. As I mentioned in the original post, this worked *before* reloading the phone. (Side note: My other SMTP/POP3 mailbox works perfectly.)
This is a first for me. STRANGE.
