Happy new year every body :) I've experienced lots of issues with Kmail since 17.08.
This might be related to <https://bugs.debian.org/cgi-bin/bugreport.cgi? bug=885182> It might be related too with the new support for Oauth: there were no oauth support before. 1- Difficulties to retrieve mails from Gmail Gmail accounts mails are usually no longer retrieved. (that is, mails sent to gmail accounts of mine). Akonadictl restart seems sufficient to fix that. I haven't observed relevant error messages. Beside maybe this one: org.kde.pim.imapresource: Session login cancelled (There are plenty of error messages, but they remain, even when mails start flowing again) When oauth wasn't implemented, I had no issues with gmail, ever. 2- cpu usage surges I often, but not quite as often as above, have cpu usage surges like so: mysqld 45%; akonadiserver 30%; akonadi_maildir 15%; kmail 10% The surge doesn't drop down by itself. akonadictl restart is sometimes enough to fix it. Sometimes a system reboot is all I've found to help. 3- "critical security alert" from Google I've got a bad security alert from Google from using Kmail, which never happened before. Best, Chris
