Hi again,

To be a bit clearer wrt my questions:

- are there any active efforts wrt mailman and encryption?
  any "post mortems" on former ones? 

- are some of you interested in mailman+encryption efforts? 

I btw expect autocrypt integration to be significantly 
simpler than previous efforts that dealt with keyservers IISIC.
