Thanks all,

I downloaded the XPSMTP80.DLL and added it in database. Now I able to generate the mail.

But I think that the dll file XPSMTP80 was made by some person with the scripting, which I downloaded from the http://www.sqldev.net.

But I am unable to understand how it works, because we can't see the code....

Can someone tell me...

Thanks to all.
