For my "annoying other servers by delay" needs, I go with 20+ Seconds 
"SMTP prompt Delay", it kills most Virus email engines, and annoys and 
lowers the rate of Spam senders... and it's just a setting on the CGP, 
no additional software/server/appliance to broke down and fix later.... 
give it a try on tuning the CGP's Edgegate (comercial name of all the 
security settings on CGP)
 </IMHO>

Of course having a spam filter or plugin will help you out too.

Greylisting doesn't worth it...
