Ok, I had

   deny    message = unrouteable address
          !verify = recipient


which I just changed to

   deny    message = unrouteable address
          !verify = recipient/callout=2m,defer_ok,random


I assume the defer_ok is what I want to avoid rejecting valid mail
that I cannot verify due to the main MX being down for some reason...

However, after I did this, I could not send to the exim list! (I
also tried without the random).

What am I missing?

Thanks
Chad
