cryptlist | hacky mailing listserv written in Python and support

Edit cryptlist.py. The list settings are all at the top of the file.
Create the list keyring in the gpg directory 'gpg --homedir . --gen-key'. It is recommended that you note that this key is for a mailing list in the key comment. Note the key fingerprint since you will need that in a following step. Enter an empty passphrase for this key.
Export the list public key 'gpg --homedir . --export --output list_key.key list@example.org'
Sign the key with your regular key so other may know that they are getting the correct key 'gpg --import list_key.key; gpg --sign-key list@example.com'. Ensure that the fingerprints match at this step.
Import the signature back into the list keyring 'gpg --export --armour --output list_key.asc list@example.com' and then 'gpg --homedir . --import list_key.asc'. Keep list_key.asc around as that is the keyfile you will want to distribute (if you aren't putting the key on a keyserver).
For each member of the list for which you have a public key you must add the key to the list keyring. As the list will trust every key on its keyring you should not configure gpg for the list to automatically retrieve keys from a keyserver. You import keys using the add_keys.sh script.
Finally add the cryptlist script to the mail filtering system. See the next section. Once this step is completed you should be able to send some test messages successfully.
If you are using a POP3 or IMAP mailbox with fetchmail then you can easily set Cryptlist to be the script called on reception of any email.
