[1] introduces an issue when a response is sent to an aliased email.
In that case, it is intended that the message should be created
by the owner of the alias by [2]
Which breaks the assumption of made in the first commit, as the message
is being passively processed by fetchmail.
This causes the owner of the alias to never be notified on reponses
in cases where the message could be an alias update.
i.e. on any model where the alias applies.
Because the responses are assumed to have been authored by the owner.
As we do not actually care who creates the message records
and deciding the alias owner 'created the message' does not
actually make sense.
We make sure messages are created by odoobot even
if the message was sent to an alias address.
