Thanks Rick.

I need that email handling for a shareware application that would email small pictures. I want to distribute on the net to thousands of people(hopefully) and I thought the best would be to use what they have on their computer, this way thay can have a history of what they did. It's something I do in my spare time.

I didn't touch the email client aspect, I don't really know how it works but and I suppose if I would need my own smtp and everybody's emails would go thgough that right ?

Any further advice is welcome.
