Use of SO_OBJECT_SEND directly to e-mail

Hi,

The FM SO_OBJECT_SEND works fine if i send it to a sap-user. With forwarding (SO12/SO36) I can redirect the sapmail to Outlook. All works well.

My requirement is that i can send an email from SAP (46c) directly to an external emailadres. I need to fill the receiver list differently, but how? Whatever I try, I get the raise 'OBJECT_NOT_SENT'.

Any suggestions?
