How to resolve "Report Server has encountered a SharePoint error. (rsSharePointError)"

Unfortunately i have faced this error while integrating SSRS2005 with MOSS2007.
I googling a lot n finally i configured all the options once againg through RSCongfiguration Manager.

I have the issue with email settings.

U need to configure email setting properly.Other wise u would get the following error.

"An existing connection was forcibly closed by the remote host at System.Net.Sockets.Socket.Receive(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags) at System.Net.Sockets.NetworkStream.Read(Byte[] buffer, Int32 offset, Int32 size) "

Once u did every thing properly u should Subscription through email.
