[Exim] Re: routing to primary MX only

hi,

to check if the prb came from the fact that redirect_router has no effect if the
new generated address is the same as the old one,
i have tryed all the possible setting in the loop_mx router for

check_ancestor
repeat_use

(false, false) (false, true) (true, true) (true, false)

and in each case i get (when using exim -bt)

unroutable address,
and the loop_mx is used only once whereas i tryed with a domain containing a lot
of MX reconds

thanks for your help
