All you have to do is generate a new key which is used to encrypt
messages which are sent by the subscribers to the mailinglist and which
is used to sign the subscribers' keys.
This is how the encrypted mailinglist works:
When someone what's to sent a message to the mailinglist he encrypts the
message with the mailinglist key.
The mailinglist manager receives the message, decrypts it, re-encrypts
it for all subscribers and then sends it to the subscribers. In order
to protect the privacy of the subscribers the message should be
encrypted for each subscriber separately.
BTW, you have to handle at least two cases. Old-skool inline encrypted
messages and PGP/MIME encrypted messages.
