I've so far been unable to make the following work:
I have a small cluster with a master node ( called bayes.bc.edu on
the public network, and called master.cl.bc.edu on the internal
10.0.0.0 network). and a number of nodes which are purely on the
private network.
I want the master to receive mail and deliver locally (or use .forward
and alias rules) to messages sent from the nodes to user@master, and I
want it to relay non-local addresses to my campus relay host which is
another machine.
The relay part works ok, all mail addressed in a form that my campus
relay host recognizes gets delivered. The problem is that mail to
user@xxxxxxxxxxxxxxxx (the internal name) gets relayed to the campus
relay which does not know about the host name master.cl.bc.edu because
that is defined on a private DNS server for the cluster, and the
campus relay rejects the message.
How can I get my cluster master to not relay messages addressed to
@master.cl.bc.edu?
The queueing/resource manager (torque/pbs) wants to send automatic
status messages to user@xxxxxxxxxxxxxxxx and that cannot easily be
changed.
Mail MTA is postfix for both master and nodes
Some postfix settings on the master.
myhostname = bayes.bc.edu
mydomain = bc.edu
myorigin = bayes.bc.edu
inet_interfaces = master, localhost
mynetworks = 10.0.0.0/24, 127.0.0.0/8
relayhost = mail.bc.edu
and some settings on the nodes
mydomain = cl.bc.edu
myorigin = bayes.bc.edu
inet_interfaces = localhost
relayhost = [master.cl.bc.edu]
Thanks for any help,
Tony Schreiner
