A bit late, but Postfix has rate limiting

See the transport settings.  Basically you can setup a specific 
transport for a certain destination and then throttle it to X messages 
per whatever.  The only thing is that if the mails are literally being 
thrown away silently then you might prefer to go the custom code 
solution so that there can't be any mishaps due to say mailserver being 
restarted and stats being reset leading to mail loss, etc

Good luck
