The new list currently has footers removed duri= ng testing.=C2=A0 I am not pleased with the need to remove the subject tag = and footer to be more compatible with DKIM users.

Lists can do what are effectively MITM attac= ks on people's messages in any way they like, if they resign for the me= ssages themselves. That seems fair to me! =C2=A0:)
