How to set up filter in ProtonMail on the SimpleLogin youtube channel doesn't reflect Proton mail's current filter UI.
The Proton mail filter page automatically generates Sieve code that skips the rule if spam is detected, which defeats the purpose of creating a rule to bypass spam detection (for my purposes, I went into the Sieve code and removed that part of the Sieve code).
The From addresses I get from SimpleLogin no longer ends in simplelogin.co or simplelogin.io, although the Reply-To: addresses do (for me, I see this change starting sometime on October 22nd.). I'm fine with the change, but it affects how the filter needs to be specified (this may apply to gmail and Outlook, too).
For Proton mail, a rule that acts as a non-spam backstop should probably be the last rule in the list of rules.
