Since 31/05/2022 it is no more possible to check the email of my gmail account using POP3. Fix would be to move to XOAUTH2 authentication method, but it is not available for POP3 resources. STEPS TO REPRODUCE 1. Create POP3 account in kmail 2. Change the Authentication method in the settings OBSERVED RESULT XOAUTH2 is not available in the list EXPECTED RESULT XOAUTH2 is expected to be here. Google seems to support it: https://developers.google.com/gmail/imap/xoauth2-protocol SOFTWARE/OS VERSIONS Linux/KDE Plasma: Debian stable (bullseye) Kontact: Version 5.15.3 (20.08.3) KDE Frameworks 5.78.0 Qt 5.15.2 (construit sur 5.15.2)
