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.

    Warn admins about outgoing s2s connections that are refused due to
    invalid or untrusted certificates
...

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

Similar to mod\_watchregistrations, this module warns admins when an s2s
connection fails due for encryption or trust reasons.

The certificate shows the SHA1 hash, so it can easily be used together
with mod\_s2s\_auth\_fingerprint.

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

    modules_enabled = {
        -- other modules --
        "watchuntrusted",

    }

    untrusted_fail_watchers = { "admin@example.lit" }
    untrusted_fail_notification = "Establishing a secure connection from $from_host to $to_host failed. Certificate hash: $sha1. $errors"

  Option                          Default                                                                                                         Description
  ------------------------------- --------------------------------------------------------------------------------------------------------------- --------------------------------------------------------------------------------------
  untrusted\_fail\_watchers       All admins                                                                                                      The users to send the message to
  untrusted\_fail\_notification   "Establishing a secure connection from \$from\_host to \$to\_host failed. Certificate hash: \$sha1. \$errors"   The message to send, \$from\_host, \$to\_host, \$sha1 and \$errors are replaced
  untrusted\_message\_type        `"chat"`                                                                                                        Which kind of message to send. `"normal"` or `"headline"` are other sensible options
  untrusted\_ignore\_domains      Empty                                                                                                           The domains that this module should not warn about
