SQL Mail on SQL Server-64 Bit

I am trying to use the xp_sendmail feature of SQL Server 2005 (64 bit) running on Windows 2003 server. Unfortunately here's what it complains when trying to execute it:
SQL Mail does not work with the 64-Bit version of SQL Server.
What will be my other alternative? Appreciated some input.
Thanks,

Service Pack 1 fixed this for DB Mail. I was just looking at http://blogs.msdn.com/sanchan/archive/2006/04/23/581639.aspx which says this.
See http://msdn2.microsoft.com/en-us/library/ms187891.aspx for SQL Mail to DB Mail conversion, this is what you want to use in SQL 2005. General how-to setup database mail: http://msdn2.microsoft.com/en-us/library/ms188298.aspx

I am using dbmail which uses SMTP instead of MAPI without any issues...

What is your sql build ?

Thanks for the email.
I am running SQL 2005 with SP1. Let me see, if SP2 is available for this platform. if yes, then i shall download and apply SP2.

Thanks for that sp2 link. Has anyone found out how to customize? Article says: "You can now customize parameters that are passed to DatabaseMail90.exe"
