Altering originating address using simple MAPI

Hi All

I want to use the environment's shared session with the smtp server, but I want to change the "From address" and "From display name" to any arbitrary string.

Can anyone tell me if it's possible to do this with simple mapi (and how to do it if it is possible)?

The only thing I can think of is to log on as the user with the originating e-mail I want to use, and then send the mail. Is there any other way?

If not, then how do I do this with extended mapi?

Thank you in advance.
