Please disregard my post. I was originally unable to download the .zip link but as soon as I posted it started working. I was unable to register the dll by the REGSVR32 'C:\program files\Microsoft SQL Server\MSSQL\Binn\xpsmtp80.dll' command as others have posted. But executing exec sp_addextendedproc 'xp_smtp_sendmail', 'xpsmtp80.dll' did work.
