SUMMARY I have several apps which use the default mail app of linux (command "mail") to send report to me as vscan, kbackup, cron etc. They send mail to my box. My mailbox is a mbox akonadi resource. My mbox is a file which name is <my name> in /var/spool/mail/. I can check that these mails are in my mailbox by using kate. OBSERVED RESULT In kmail these mails are not listed. EXPECTED RESULT In kmail these mails are listed. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.21.2 KDE Frameworks Version: 5.80.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION In the past there were no problem.
