"Can I run my Mail-in-a-Box at home? No. "
More like “Should I run my Mail-in-a-Box at home? No.” Still get marked as spam by gmail. rDNS is a killer
But can get a negative score from Spam Assassin on dkimvalidator.com
I made some notes, mainly for myself, but wrote it up in case it helps anyone else. The server is Ubuntu 18.04 running LXC (Linux Containers). A virtualization method for running multiple isolated Linux systems (containers) on a control host using a single Linux kernel. My home router has a single IP address, with alas rDNS (reverse DNS resolution) not controlled by myself. My iSP does not block ports.
Thanks for the project,
