[exim] router setup problems

I'm running exim4 and have a exim.conf file. I need exim to redirect mail
for postmaster@localhost and root@localhost to me@???.



I have 2 routers set up, pretty much just following the example.conf. The
first determines non-local addresses and palms them off to smtp. My second
router does a /etc/aliases lookup which has entries like this:



postmaster = root

root = me@???



I get nothing but bounce messages stating that my messages are unroutable.
If I send a message to postmaster, it is redirected to root@???.
If I send to root it is redirected to me@???. No matter if I send
to postmaster, root or me@mycompany all messages bounce. Where might I have
gone wrong here?



Cheers

Mike
