If you have a good whitelist this won't bother you.

Why make it obvious that the addresses are spamtrap ones?
Just hide a comment somewhere on the homepage that only harvesters will see
but
not people who browse your web site ( unless they read the html source ).

I have been hit where a spammer has used one of our addresses as a reply_to
address.
No worries. spamd doesn't even break a sweat. The mail doesn't ever hit our
server
and the only servers that have the problem are the mail servers that believe
the forged reply to address
as they bang their heads trying to deliver the bounced mails. They should
try spamd :-)

g'day
