HI Meghana,
There is nothing as such. Let me outline on what we did in past.
1) Configure SMTP Node connection for mail server ( *@XYZ.COM)
2) Set default outgoing server domain ( ABC.COM)
When it comes to functionality, lets say you want to trigger an email at the creation of notificaiotn in SAP, the use BADI NOTIF_EVENT_POST.
You need to check with your ABAP for what information you need to send using email and accordingly you need to use FM SO_DOCUMENT_SEND_API1.
Regards,
Amol
