The mailing list for listmasters using Sympa

[Rene Pfeiffer <address@concealed>]

Hello!

I am using SYMPA for over a year now but I never touched the S/MIME
configuration [*]. A few days ago someone on a hacker/coder mailing list
brought up the topic of having encrypted mailing lists with GPG/PGP public
keys. The points that were discussed can be summarized by the following
"requirements":

 - public keys are used for encryption
 - the list server should encrypt the message
   a) individually to every list member
   b) or to all list members
 - the list server should have the ability to retrieve subscriber's public
   keys from keyservers
 - the list server should be able to receive public keys from subscribers
   and relay them to a local keyserver
 - every mailing list should have its own public key for posting messages

Did anyone of the SYMPA users or developers think of such a scenario? Is
this feasible? Did someone do some experiments? The lists of this kind would
operate with a small number of users (let's say a few hundred). The list
manager could use public keys from a dedicated keyserver nearby.

I think it would be good idea to think of a plugin API for these kind of
"crazy ideas".

Best regards,
René

    for a local CA.
