Implement reliable stanza delivery using XEP-0198 - Stream Management
Submitted by Michael Gratton

Currently, intermittent network connections can cause gabble to regularly drop messages and other XMPP stanzas, both sent and received, since XMPP does not by default implement reliable stanza delivery. This is important since users have no feedback if a message has been successfully sent/received or not, and can result in social repercussions if a message is lost.
XEP-0198 adds an official way to implement reliable delivery, and at least jabberd2 implements it on the server side, thus gabble should support it, too.
