IMHO, blacklisting some one just because it sent a message to a spamtrap
is a bad idea.
One situation, not the only one, where this is a bad idea is about ISPs
outgoing mail servers, where you can have both good and bad trafic
flowing from.
Sometimes you can accept blacklisting this, but sometimes not. When not
you shall manage a whitelist of servers not to blacklist when they send
messages to spamtraps - not allways feasible.
