Not a big deal, you may think. The tricky and clever thing about spamPepper is that the challenged sender only gets to see your nickname, not your email address. While it will be easy for friends and colleagues to connect the nickname with your email address (or, simply, the challenging message with the last email they sent), spammers have no chance to guess the right address. Thus they will fail to authenticate even if they or their robots would attempt to reply.
Unfortunately, the same applies to senders of newsletters and to mailing lists. That's why it's important to authorize newsletters manually in spamPepper, ideally at the same time when you sign up. I have registered the "about.com" domain, for example, to make sure I get all the About newsletters I have signed up for.
