The only error is ** Unrouteable address. As I said earlier in the
thread, the only mail that has problems is an external address sending
to an alias that is also an external address. It is primarily
forwarding to a handful of blackberry mail accounts, and a couple home
mail accounts. The internal host is definitely allowed to relay, there
are no other problems. Internal users can send mail to the aliases and
have them forwarded with no problems.

Here is a slightly obfuscated snip from the log, the first section is
the mail coming into the smarthost from outside and being sent to the
internal host. The second section is the same mail coming back out and
getting stopped.

Thanks,
