ProtonMail inbound on Arrow server

Finished Scheduled on 2021-10-14 00:42:00 Estimated finish 2021-10-16 00:43:00
For 24 hours inbound mail from Protonmail will be blocked on the Arrow server. This is a protest and a sign of things to come for Protonmail, if they continue to refuse to take proactive action against an intentional phishing campaign that is merely iterating through free accounts on their system with impunity. If this impacts you, and you are a customer of Protonmail, please direct your complaints to the ones responsible: Protonmail.

2021-10-14 20:25:00 Adding +24 hours to this. From our estimate it impacted 1 email that wasn't exactly one of the abusive emails we were trying to block. That's better statistics than almost every other block, and we need to keep sending a message to Protonmail.
