Comment 2 for bug 1776492

Kombu actually supports the mandatory flag.

@kgiusti the error you see in your tests is [1] ( I fixed it, now the tests work)

Mandatory flag can't be used on "memory" transport in kombu since "memory" transport does not follow AMQP protocol, see [2]

btw we are working on "mandatory" flag implementation, see [3],[4] and [5]
