Sending mail to Internet address from SAP system

Hi...

My requirement is to send a mail to an internet address say ABC@companyid from SAP.

I have used a FM So_New_Document_Send_API1 for the purpose.For this I have provided

e_mailrec-receiver = w_emailid.

e_mailrec-rec_type = 'U'.

APPEND e_mailrec.

But I get an error msg in SOST, that the route from (SAP server) to (mail id) not found.

Instead of internet address when I give rec_type as B i.e. SAP USER it sends a mail to my SAP inbox.

I have also checked SAPConnect, and it is fine.

Is the above FM only for sending mails to SAP id, then wats the FM for sending mails to internet address? Its just sending a 1 line mail without attachment.

P.S: I have gone through search in sdn so please don't provide me with links to other threads.

Reply only if you can actually help and know wats this about.

Thnaks and Regards.
