I’m looking to setup a simple mail relay using openSuse 11.0. I have
found countless threads and documentation, but I think I may be
over-thinking this a bit.
This will just be used for things like mail alerts from servers,
storage devices, printers, etc. Sending to an outside exchange server.
I am fairly new to suse/linux. What do I really need? I believe I can
do this with just postfix?
That’s trivial, just configure postfix to relay to an external server
and to accept mail from all interfaces (so that other machines on your
subnet can use it). This can be done using the YaST postfix
configuration.
You have to allow your LAN machines to use the mail server. I’m not in
front of a 11.1 machine at the moment so I can’t tell you where it is in
YaST but you have to allow it with mynetworks_style=“subnet” in
/etc/postfix/main.cf. It may be at “host” at the moment.
No that’s fine, you can edit main.cf yourself. But YaST will no longer
control the config once you change main.cf manually. It is possible to
control everything, perhaps slightly indirectly by editing
/etc/sysconfig/postfix.
