Dear Debian-community, irregularly an x-window pops up with message: /The server (my e-mail-server at my standard internet-provider) rejected the user-name and the password. Login failed. Server response is: A000002 NO Authentication failed./ BUT nevertheless my mail-client (Kmail) d o e s receive every message. Serveral attempts by myside to locate the error - believed that problems in Debian 11 with kontact/kmail/akonadi/ could be the reason. Anyway distribution-tests in my VM (Debian testing / Debian oldstable / Manjaro) lead to the same message. So can I find the reason within my Debian 11 bullseye o r is this is a special behaviour within the mailserver at my provider ( A1.net in Austria) This only appears within Linux - my (dual-boot) Windows 10 or my smartphone-app runs without such message !
Any help / tips appreciated. Greetings Herbert
