i can't ignore thoses 3 host, because in my config, the 3 host are secondary MX
for each other.
I realy need to extract MX record with higher priority than the localhost for
the curent domain.
anyway, i think i need to use a ${perl statment because there is no looping or
sorting in exim syntax.
the strange thing is that there is a @mx_primary var in exim, but no way to get
the primary mx for an arbitrary domain
