This chapter from Postfix walks you through the server requirements. 2 only) Try to It might be different for you since apparently the issue occurred when upgrading NC, but in our case it seems the issue was because our mail server updated its security and upgraded to TLS 1.


This tutorial assumes that you are doing the installation on a fresh system with at-least 2GB of RAM. Recently I covered: The Devilbox is a modern and highly customisable dockerized PHP stack supporting full LAMP and MEAN and running on all major platforms. yml file for our code those values will be used.
