Setup sendmail to send outgoing mail to relay server


All,
I am trying to setup sendmail on my redhat box to send all outgoing mail to an existing server. That server will then forward it on to the address. I know I need to configure the .mc file and recompile, but not exactly sure what lines to edit. Any help?

-Mark

i use postfix in our RHEL4 boxes relaying to an AIX machine
that is using sendmail.

in case you are interested to switch to postfix, i edit

/etc/postfix/transport

and added this line:

* :[a.b.c.d]

# a.b.c.d is the address of my aix machine

and in /etc/postfix/main.cf:

transport_maps = hash:/etc/postfix/transport
relayhost =

of course, in the AIX machine, my RHEL4 boxes are allowed to
relay.

but in my other aix systems, i've set in their /etc/mail/sendmail.cf
files the ff:

DSmachine_where_i_can_relay

and has cron job running with this command:

export NSORDER=local
/usr/sbin/sendmail -q


(since sendmail in my aix systems are not using
DNS for name lookups).

also, in machine_where_i_can_relay, the aix "clients" are
allowed to relay. i have /etc/mail/relay-domains with the following:

machine1.yourdomain.com
machine2.yourdomain.com


hth.

You need to add this line (or uncomment it if it there already):

define(`SMART_HOST',`smtp.someserver.com')

Then build the .cf
