Hello Darren,

YOu can set it up on Exch 2k/2k3 on the SMTP Server properties, on its advanced 
settings, in the last tab (can't recall the name and tôo lazy to TS)

But, it's won't produce the desired effects ;) I own GFI MailEssentials and 
that's the factor that least catches spam (and also reject messages that 
shouldn't be rejected). You'd better off getting the right tool to fight the 
problem =)

How do you set up Reverse DNS on your Exchange Server to reject messages
that don't correspond to the IP address/Reverse DNS entry.  This tactic is
usually used to block spam.
