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'.
