it used to run pretty well on one, but the lead dev made significant changes making it a bitch to run without doing it "his way". What I ended having to do was change my nginx configuration so that I was using the one in his docker-compose directly as opposed to running my own that would point to his for mail related needs.
I forgot what exactly broke but when I reported that breakage I basically got told "tough shit, it works on my set up", I don't remember being demanding or impolite just reporting the issue and asking if he was aware of/had plans to fix it. Not too long after the product was acquired and I chalked it up to enshittification and shitty dev being a shitty dev.
