Adding PGP capability to Majordomo

This sounds great, though I am somewhat confused about the mechanism and effect... just giving Majordomo a keyset would not (at least to my understanding) cure the problem of an??? recipients resulting in new an??? accounts. Perhaps I am missing something fundamental here, but what would this buy us? Lyman Finger lrh@crl.com for PGP 2.4 Public Key Block.
