I'm going to try all that was suggested, but just to give you some more
insight.....
The Firewall/Proxy is TIS FWTK on RH 5.0.....The mail server is on the
inside of the Firewall i.e on The LAN..............It uses private ip
address......therefore the only way of knowing the ISP's mail host is if
it forwards all mail that is destined externally to the Firewall/Proxy
which should then send them out right?
Presently, hip hip horay.....I can send mail from the Firewall/Proxy
outside of the domain......and it reaches external mail hosts......
The present problem though is that my mail server on the LAN doesn't know
how to forward mail destined for outside the domain to the Firewall/Proxy
the error returned was "Transient parse error"....
I need to know though, does the Mail server on the LAN with a private ip
address needs to know any ISP's ip addresss? for example the DNS since we
use their DNS...
I was thinking the Firewall/Proxy knows it so that should be ok....
