G'day Sean,
Steve Bennett stated for the record:
Yes, you add 10 lines of spam to every message you send.
No, I don't. I add an information-dense attachment that no modern mail client displays inline.
On the assumption that Mozilla Thunderbird counts as a "modern mail client": bzzzt!
My mail client handles PGP keys appropriately (at least, to my limited level of understanding, it does), and no other poster to this list seems to "add 10 lines of spam to every message" except you. This includes those who use PGP. I think the problem may well be at your end.
(In any case, as someone once said, PGP doesn't guarantee that you are the sender of the message: it just means that, if you aren't, nobody will believe you.)
