I know there are some out there that have reported problems with sending from their bb using yahoo, but I'm also having a problem sending from Lotus Notes using my bb. I can receive from all my mail find (yahoo, Lotus Notes, gmail), but I can only send from gmail. Any suggestions/ideas?

Thanks,

Yo.

Hope that gets you going in the right direction.
