I have two SMTP connectors, one is using UNIX smart host for Internet mails,
the second one is for external routing/forwarding because we have many
configure the second SMTP connector using DNS. However, the DNS is on an
UNIX as well. The external domains are not allowed in the Unix DNS. So I
want to try to add a HOST file including all external domain names. I
when the second SMTP connector tries to relay external domain names it will
look at the local HOST file first to resolve the domain names.
Am I right, should it be working?
