mod_smacks: also count outgoing MAM messages mod_smacks doesn't count outgoing MAM messages, which causes warnings in Prosody such as: > The client says it handled 41 new stanzas, but we only sent 2 It seems mod_smacks is in the wrong here and that it's too strict in trying to determine what is a valid stanza to count. In RFC6120: > Definition of XML Stanza: An XML stanza is the basic unit of meaning > in XMPP. A stanza is a first-level element (at depth=1 of the stream) > whose element name is "message", "presence", or "iq" and whose > qualifying namespace is 'jabber:client' or 'jabber:server'.

...

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

[SIFT][XEP-0273] is a technology to allow clients to filter incoming
traffic on the server. This helps save bandwidth, etc.

Compatibility
=============

  ----- -------
  0.7   Works
  ----- -------

Quirks
======

This implementation is a work in progress.

-   Stanzas to full JIDs get sifted correctly
-   Stanzas to bare JIDs are currently allowed/disallowed for all
    resources as a whole, and not for individual resources
-   Presence is only sent to available resources, and probes are not
    sent for unavailable reasources
-   This module currently does not interact with offline messages
    (filtered messages are dropped with an error reply)
-   Not tested with privacy lists
