Postfix (SuSE Linux Mailserver)
mynetworks
in
/etc/postfix/main.cf
to allow relaying.
mynetworks= 127.0.0.0/8, 10.10.0.0/16, 192.168.0.0/24This parameter might be disabled with a comment sign. If this is the case, remove the comment sign. Then restart Postfix:
openexchange:~ # rcpostfix restart
From this moment on, all clients from the above-specified networks will be able to send messages directed to external domains to the server. The server performs the relaying function. Make sure you only enter your own network. Otherwise, you will create an open relay that can be misused by SPAM senders.
