Ok, I see. I need to modify my configuration as well. Still one
question:
Can I define 2 files in mynetworks like this :
mynetworks = !hash:/etc/postfix/insiders, hash:/etc/postfix/outsiders
With Ip adresses in the files ?
Will this work or should I define
mynetworks = hash:/etc/postfix/insiders , hash:/etc/postfix/outsiders
With "!ip_addresses" in the insiders file and "ip_adresses" in the
outsiders file ?
Thanks for your help.
