Sendmail Relay Question

[rmueller58]

I have a question about how to define sendmail as a client on my HP/UX box and relay off of a Linux box?

We have our UX box on the inside zone of our network, We do not have DNS resolver defined on it as it had caused problems.. What we want to do is send any sendmail items via an IP address relay to a Linux Box (that sits in a less secure zone) and has the ability to send out mail from that point.

It would seem we should be able to use Sendmail on UX as a client of the SMTP server on the linux box..

Any ideas appreciated..

Shalom,

in sendmail.cf

Change

DS

to:

DShostnamelinuxbox

or

DS
[192.168.0.10]
# where the ip address is the ip addres of the linux box.

/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start

Linux will have to explicitly define the HP-UX box in its access file:

/etc/mail/access

hostnamehpux RELAY

or

ipaddresshpux RELAY

Then sendmail macro will need to compile the macro database on the linux box.

# script to build the sendmail from the macro database
/usr/bin/newaliases
cd /etc/mail
makemap -r -v hash access.db < access
makemap -r -v hash access_db < access
makemap -r -v hash domaintable.db < domaintable
makemap -r -v hash domaintable_db < domaintable
makemap -r -v hash genericstable.db < genericstable
makemap -r -v hash genericstable_db < genericstable
makemap -r -v hash mailertable_db < mailertable
makemap -r -v hash mailertable.db < mailertable
makemap -r -v hash virtusertable.db < virtusertable
makemap -r -v hash virtusertable_db < virtusertable
cp -p /etc/mail/sendmail.cf /root
m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

service sendmail restart

As usual you have it down to a science.
