[SLE] postfix configuration w/Yast

[Tom Allison]

I ran into a very small problem with postfix. It's the last of my
tweaks to get this working.

First, my network.

postfix is in a DMZ (192.168.0.0/24) and I send all my mail through my
LAN (192.168.1.0/24) connection to the DMZ boxen.

However, I currently have my mail client (Mozilla) configured to send
mail via the DMZ SMTP server and not localhost.
In order for this to work, I have to modify the postfix/main.cf file to
include:
mynetworks = 127.0.0.0/8, 192.168.1.0/24

But I can't find anyway to set this through the /etc/sysconfig files and
once I set this, all changes through the sysconfig files are
subsequently blocked.

I'm trying to find some compromise where I might add a special tag to
the sysconfig files to provide this extra configuration item.
At least this way I could have all my configuration settings managed in
one place (/etc/sysconfig/) even if I can't interact with 'mynetworks'
through Yast.


My alternative is to configure postfix on every machine as a localhost
delivery for email.
I could do this easily enough because I'm working in my house as a pure
linux network.

But I'm also trying to set this up for my brother who uses a
heterogeneous network of Linux and Windows (all version) and will still
require a smtp delivery server.

Is there some way to "hack" in a special configuration item in the
sysconfig files?

I once saw someone who hacked in some code to use qmail instead of
postfix/whatever and that was a customized line, but was in Suse 7.? or
earlier.

POSTFIX_ADD_mynetworks="192.168.100.0/8, 127.0.0.0/8"

Don't know if this ADD thing work for all configuration files, but it
doess for config (any variable, it works). Curious, and nice :-)

Use the "POSTFIX_ADD_" Syntax in /etc/sysconfig/postfix:

POSTFIX_ADD_MYNETWORKS=......

add the following to /etc/sysconfig/postfix;
## Type: string
## Default: 127.0.0.0/8
POSTFIX_ADD_MYNETWORKS=""

You can now access it the the sysconfig editor in yast and add this
parameter to Postfix through Yast. HTH

This is cool!

From other posts it seems that this is rather unique to the

/etc/sysconfig/postfix file and not ubiquitious to the /etc/sysconfig/
files.
But it will certainly help a lot.
