I strongly support a DO NOT E-MAIL list. I get 20-25 spams e-mails per day at work and it consumes far too much time to pick out the valid e-mails in additional to the additional volume on our servers. Week-ends I get 75 or 80, so Monday mornings are a pain. I should not have to devote my work hours sorting through spam. Subject lines should have to describe what is in the message - not some vague notation.
