The mailing list for listmasters using Sympa

[Adam Bernstein <address@concealed>]

We've got somebody who wants to start using S/MIME encryption, but the 
process of obtaining personal certificates is too complex to expect all of 
their users to manage it.  Under the current scheme, those users will only 
receive a message about "This message was sent encrypted and we don't have 
your key", instead of the actual content.  They would like to have an 
option of selecting opportunistic or "if possible" encryption, where users 
whose keys have been collected by Sympa will receive the message 
re-encrypted, while everyone else will receive it in plaintext.

Is there any interest from Sympa in providing that kind of choice?  I can 
see why it might violate rules about distributing in plaintext some data 
that somebody thought needed to be encrypted, but if it's a deliberate 
choice by the list owner, would it be acceptable?  And technically, would 
it be easy to alter the code?  I think so, but I wonder if I'm wrong about 
that.

Thanks!
