Hi Larry - I just found out (thanks to something @jeffschwenk told me at Sage Sessions in Chicago) my Socialcast messages have been going to junk for the last few months. If this is still an issue, please let me know - I will do my best to assist.
The short answer is we have done it. I believe it was kind of a pain in the butt (technical term) - would need to verify with my much smarter technical guys though.
LMK if you still need the info.
