Grrr. I use a mailer here (that I'm developing) that automatically encrypts outgoing mail for user X if "<X>" can be found in my pgp keyring. Unfortunately some comedian has published the key below...

Type bits/keyID Date User ID pub 384/99CBA7 1992/11/15 Polyanna, c/o <cypherpunks@toad.com> 1 key(s) examined.

so if I use this mailer when posting to cypherpunks, it gets encrypted for this idiot. I guess this is something we mailer writers will just have to allow for. Looks like I'm about to add a stop-list... (removing it from the keyring won't be good enough, because next feature planned for my mailer is to look up the fingerable key-server if it isn't found locally...)

Keep up the good work in writing that mailer. I think a stoplist is good for more than just jokers such as above. There are those who have published pgp keys but they don't have an easy-mchanism for reading pgp messages, so most mail to them shoulnot be encrypted.
