Even if you force people to keep a correct (and current) email address
in the User ID portion of the PGP key, (which is too restrictive as humans
are lazy by design), a spamaziod could make some junk PGP key with your
email address, add it to a keyserver, then make the subscribe request. Might
also may it impossible for the spam victim to get off the list!
If you want a Majordomo list server that uses PGP to provide encrypted
administration and encrypted distribution, feel free to grab by code:
Should be a could start for any PGP code enchancements to Majordomo.
