You may be right in case of typical "medium+ load production server".
[ I would not disagree strongly without "practical tests" first ]
In my case I do not expect the spamtrap server to achieve 
peak minute throughput higher than one message per second 
(after iptables protections) unless DDoS occurs :-)

More precise description in my case would be 
"avoiding accumulating excessive evidence" :-)
[ I use trapped spam to send abuse reports via spamcop.net ]
