there exist several pieces of folk wisdom: - "you cannot run your own mail server in 2025, this is too hard and time consuming" (completely false, i've done this since ~2010 with minimal ongoing maintenance) - "you can do it but gmail will sort your mail to spam" (partially true and what i want to talk about here) recently, my hand was forced: i had to migrate my mail server across providers and regions. it's unimportant why but important what the result is. 1/3
