mod_firewall: Update user marks to store instantly via map store The original approach was to keep marks in memory only, and persist them at shutdown. That saves I/O, at the cost of potentially losing marks on an unclean shutdown. This change persists marks instantly, which may have some performance overhead but should be more "correct". It also splits the marking/unmarking into an event which may be watched or even fired by other modules.

Introduction
============

This module was written to encourage usage of End-to-end encryption for chat and MUC messages. It can be configured to warn the sender after every plaintext/unencrypted message or to block all plaintext/unencrypted messages. It also supports MUC and JID whitelisting, so administrators can for example whitelist public support MUCs ;-)

Configuration
=============

Enable the module as any other:

    modules_enabled = {
      "e2e_policy";
    }

You can then set some options to configure your desired policy:

  Option                                 Default        Description
  ------------------------------------   ------------   -------------------------------------------------------------------------------------------------------------------------------------------------
  e2e\_policy\_chat                      `"optional"`   Policy for chat messages. Possible values: `"none"`, `"optional"` and `"required"`.
  e2e\_policy\_muc                       `"optional"`   Policy for MUC messages. Possible values: `"none"`, `"optional"` and `"required"`.
  e2e\_policy\_whitelist                 `{ }`          Make this module ignore messages sent to and from this JIDs or MUCs.
  e2e\_policy\_message\_optional\_chat   `""`           Set a custom warning message for chat messages.
  e2e\_policy\_message\_required\_chat   `""`           Set a custom error message for chat messages.
  e2e\_policy\_message\_optional\_muc    `""`           Set a custom warning message for MUC messages.
  e2e\_policy\_message\_required\_muc    `""`           Set a custom error message for MUC messages.

Some examples:

    e2e_policy_chat = "optional"
    e2e_policy_muc = "optional"
    e2e_policy_whitelist = { "admin@example.com", "prosody@conference.prosody.im" }
    e2e_policy_message_optional_chat = "For security reasons, OMEMO, OTR or PGP encryption is STRONGLY recommended for conversations on this server."
    e2e_policy_message_required_chat = "For security reasons, OMEMO, OTR or PGP encryption is required for conversations on this server."
    e2e_policy_message_optional_muc = "For security reasons, OMEMO, OTR or PGP encryption is STRONGLY recommended for MUC on this server."
    e2e_policy_message_required_muc = "For security reasons, OMEMO, OTR or PGP encryption is required for MUC on this server."
