Hello, I have been looking into this for the better part of today. I
am using a proxy in front of postfix. In order to be able to AUTH a
user through the proxy, the proxy needs the 250-AUTH credentials to
show up.
I discovered that mynetworks disables this for those hosts listed in
mynetworks. I can of course, remove my local range from the
mynetworks, but then local machines need to AUTH to send email
through. Not all the systems have this ability.
I have tested this with telnet, and the 250-AUTH will show up if I
remove my range from mynetworks. Is there any way to get postfix to
always show 250-AUTH? Am I approaching this entirely wrong?
I could dedicate an IP to the proxy, and then enter in all the other
IP's into mynetworks, which of course would work and solve this, but I
thought I would ask the preferred method here.
Thanks.
