I decided to switch to protonmail when my mail server died because "they can do a better job than I can, it will be easier, more private, and it's worth the added cost".
Of course they can't fucking receive some of my emails, including login tokens for discord & my bank.
I just typed, in an email to their customer support, that unless they can solve this issue I'll just go back to hosting my own email server because "it seems less of a headache"
