It would be nice if toad.com would verify signatures and insert a header into the messages with the PGP User Id of every poster. Then it would be very easy for many people to filter the messages using widely available off-the-shelf mail software.

Well the obvious answer seems to me to stop majordomo at toad.com accepting ANY messages from anonymous sources but let pseudonyms post, pseudonymous posting allows the owner of the nym to accumulate reputation capital without disclosing his or her true identity. Bear in mind of course that this is a purely technical answer and I happen not to believe that anonymous posting should be stopped.
