These ended up all being pretty good tips, so thanks for the advice. I had indeed already set up SASL but the other two ended up being the key to getting all the features I wanted.
It's always rewarding but baffling how good open source software can be and how all these separate programs controlling single functions can dance in harmony. But at the same time, confusing docs and places like StackOverflow can make it hard to find all the answers you need sometimes... at least for beginners and everyone is a beginner at some point with every piece of software. Gonna get my whole website config setup, then I will probably try to convert a lot of these notes into a guide.
