Beware of anon.penet.fi message!

Currently to mail to person 1234 at penet, you send mail to anon1234@penet.fi This mail goes out anonymously from the sender, either using an existing mail address or creating one. But if one were able to reach person 1234 also with the email address, say, name1234@penet.fi the behavior could be _not_ to make this posting anonymous. To wit, the 1234 indicates that you are replying to a pseudonymous recipient, and the anon/name pair indicate whether the sender is anonymous. Thus no change in default behavior, and no new header lines. Eric
