Hallo Wietse, yes I understand Your point.
In my internal host, dns lookup is disabled. I simply would like to know how may I specified some additional hosts in case of accidents one of them. For example, in the transport table we have something like this: *example.com <http://example.com> :[gateway.example.com <http://gateway.example.com>]* *Once dnslookup is disabled, E-mail will not be deliver to the gateway. At the moment gateway.example.com <http://gateway.example.com> include MX record with 2 systems.* *mx1.example.com <http://mx1.example.com> / mx2.example.com <http://mx2.example.com>* *Is it possible somehow to specified in the transport table multiple hosts when dnslookup is off ?* *example.com <http://example.com>* On Fri, May 27, 2016 at 7:29 PM, Wietse Venema <wie...@porcupine.org> wrote: > Please read my email again.
