Want throttle or add small delay/pause to slow down SMTP connections

What SMTP server do you use? postfix (www.postfix.org) will handle this for you... But because it knows about your users etc, it only slows down connections for things that are more likely to be spammers rather than slowing down legitimate traffic...

 

 

(Slowing down ALL connections will just annoy people). However if you snoop the result codes from a generic SMTP server, you could (As hoolio suggests) use rate shaping to drop the bandwidth to some painfully low level (And send a nice long status message telling the admin what you're doing, and how to contact you if it's a mistake).
