Affected Systems
ProtonMail is experiencing an outage. We are unable to deliver mail to them at the moment. It's possible that the emails in queue may bounce back to the sender. If you get a bounce for an email sent to Proton that says "This message was classified as rSPAM and may not be delivered" that does not mean that we wouldn't have delivered it if they were online, it simply means our backup relay provider filtered it, and they filter more heavily than we do.
