Problem with sending Email

Hi Gurus,

I need to send email to some internet address.

I am using FM 'SO_NEW_DOCUMENT_ATT_SEND_API1' for this purpous.

I am sending needed parameters and my FM executes with Sy-Subrc equal to 0.

But mail is not received.

If any one faced the same situation, would be very helpful for me if he/she can throw some light on this.

If needed I can paste my sample code here.

Thanks,

Lalit Kabra

PS : I am sorry to ask the same question which has been asked thousand times earlier. But could not figure out problem.
