[SR-Users] Dispatcher with parameter use_default=1

Hello,

you have to set the priority field for each destination to ensure a
particular order there. While with text file one can consider the order
of appearance, this is no longer valid for database -- the order in a
table can be different that what is returned by "select * ...",
therefore the priority field is the one that matter here.

Cheers,
Daniel
