Some elected changelog items

Enforce E2EE

• Enforce end-to-end encryption for incoming messages.
  New user address mailboxes now get a enforceE2EEincoming file
  which prohibits incoming cleartext messages from other domains.
  An outside MTA trying to submit a cleartext message will
  get a "523 Encryption Needed" response, see RFC5248.
  If the file does not exist (as it the case for all existing accounts)
  incoming cleartext messages are accepted.
