I am using SQL Server 2000. I wanted to send mail through SQL. So I downloaded xpsmtp80.dll and copied to C:\Program Files\Microsoft SQL Server\MSSQL\Binn\DLL. Then I registered it by exec sp_addextendedproc 'xp_smtp_sendmail', 'xpsmtp80.dll'. I granted permission to public by grant execute on xp_smtp_sendmail to public.Now when I am executing this

declare @rc int
exec @rc = master.dbo.xp_smtp_sendmail
@FROM = N'MyEmail@MyDomain.com',
@TO = N'MyFriend@HisDomain.com',
@subject = N'My first HTML mail',
@message = N'<HTML><H1>This is some HTML content</H1></HTML>',

@type = N'text/html'
select RC = @rc

i tried all given information, but still unable to send mail. it returns only '1' & error of greylistng,

can anybody help me in the same.
