    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\_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
