I believe (1) should be harmless for an English language list such as
fedora-list, although there might be a case where a far-eastern poster
with a substantial .sig containing "big" characters could trigger base64
encoding of a predominantly English language message. As has been noted
before, I think there's so little spam on this list that the need for
extra measures is just not there.
