ugh, my attempt to avoid the GMail POPocalypse seems slightly successful. Most mail is getting through fine with shiny new ARC headers and SRS, but a wide range of forwarded mails from legit third party senders are now being sent to GMail…

POPocalypse update: It's Q2 2026 and I still have the ability to pull my mail into gmail via POP3 somehow (yes, I really should get around to implementing ARC instead.) @jwz

This this this. I've been saying this too! (albeit to a much smaller audience)
I miss /etc/rc.local.
update on the POP3pocalypse. it appears that the most likely thing to work in the future will be to use SMTP forwarding to gmail with ARC headers added to the mails, going by comments on @jwz 's post at: https://www.jwz.org/blog/2025/12/t…
Oh crap. Gmail is deprecating support for picking up mail from a remote server using POP3 polling in January 😭 Given that I switched to this mode due to reliability problems with direct delivery via mail forwarding, this really sucks...
