Bye bye ProtonMail

I recently blogged about my ProtonMail issues, the weird glitches with their bridge IMAP interface and their apparent lack of care that it might be silently deleting customer data - proton-bridge issue #220

I have now finally gotten around to kicking ProtonMail out of my life and I could not be happier. Gone are the days of having to run some janky Go software just to get an unstable IMAP interface. Gone are randomly changing message UIDs invalidating backups. Gone is the totally batshit way that messages can become orphaned from any folder and not show up anywhere other than "All Mail".

Suddenly I have normal IMAP that works, it even works on iOS (!) and in the webmail I can operate on more than 50 messages at once. I can in fact perform a quick operation on the entire resultset of a search. Try doing that in Proton's webmail. I have lost hours of my life to messing around just try to carry out basic operations on their platform and I'm so glad to be rid of it.
