Managers,
I have several Solaris 8 machines on a private, non-routable network
from which I need the ability to send email to the outside world. One of
the hosts on that network is a bastion between the private network and the
public network. This host is running sendmail and uses the DS (smart relay)
option to direct all of its email to our email gateway. Mail sent directly
from the bastion host to the outside world works without any problems.
However, email sent from any of the hosts on the private network addressed
for an internet host winds up queuing with the following error reported by
mailq.
/var/spool/mqueue (2 requests)
----Q-ID---- --Size-- -----Q-Time----- ------------Sender/Recipient---------

I am not a sendmail expert and am not sure if the DS option is what I should be using in the first place. I am also running a private caching-only name server on the bastion that provides name services to the private network only. I do not have MX records for the private hosts but have seen some articles on the web that suggest using a single wildcard MX record for all private hosts. I have tried this without any success. If anyone out there has had experience with this type of configuration or has some words of wisdom to impart, please email me. Your help is greatly appreciated.
