A nit about RFC1113... The RFC uses X- headers for the new encryption and authentication fields. This is wrong. The X- syntax for headers is specifically reserved for users, since no standard header will ever have that syntax. The header lines in RFC1113 are "official", even though they're not in RFC 822 (or, quite possibly, its successors). --Steve Bellovin smb@ulysses.att.com
