Over on the Mainsleaze blog, Catherine Jefferson points out that the Obama campaign is sending mail both to an address she purposely signed up to receive their mailings, and also to a spamtrap address.
What does a reputation system do with that? What should it do with that? If it's a reputation system that deals with just individual spamtrap hits, then that IP address is now tagged as having a bad reputation, because it hit a spamtrap address. But it's also sending wanted mail at the same time. A blacklist operator or an ISP postmaster might go either way on this -- you're hitting my spamtraps -- so I'll block you. But maybe my users will complain, so maybe I can't block it.
It's a bad situation for a sender to be in. They're sending mixed reputational signals. If you're really about staying in the inbox, shouldn't you be staying away from mixing bad lists or bad data into that good, wanted mail stream? I think you should.
