John, this isn't really security-related, probably best suited for
cobalt-users, but...

Your example is confusing b/c you don't mention a username and you used
"bob" in both the server and external email address and then say bob doesn't
exist.  But I think you're saying that there is *not* a user on the server
and you want to keep it that way, but fwd email for a specific email address
to an external location.  OK.

Add the following to the bottom of /etc/mail/virtusertable:

# Tab between two parts below
bob@xxxxxxxxxx     dummyuser1

Then type:

makemap hash /etc/mail/virtusertable.db < /etc/virtusertable

Then add the following to the bottom of /etc/mail/aliases:

dummyuser1    bob@xxxxxxxxx

Then type:

newaliases

Done.  Enjoy!
