Proton and Spammail protection
I am annoyed. I just tried to send an email. Again. Multiple times and always got the error 550 5.7.1. After some tries to fix possible reasons (changed IP, changed to .com instead of .me) the result is: the recipient blocked apparently proton completely? 😮💨
Not sure how this works, only annoyed and needed to vent. Never had this before. If anyone has an explanation: great I'll take it. Rationalization yay.
