POSTFIX SASL problem
I have problem on relaying from POSTFIX Debian server to another Debian server that dos not have POSTFIX installed on it.
I use PMTA to relay server and now when i have configured all working as normal, POSTFIX informs that SASL authentication failed; cannot authenticate to server no mechanism available when trying to relay to another Debian setup.
So my question is, what needs to be installed more on relay server to this SASL to work?
I added super user on relay so those thing are working. I tested this on same setup, but i had POSTFIX installed on relay Debian server.
Is this PMTA problem, or on Debian?
Any advice is good, i have looked and looked around what to implement.
