Akonadi IMAP typically maintains two socket connections to the IMAP server: one that executes the "IDLE" command and another for all other commands. If the second connection dies while the IDLE connection remains live, then Akonadi is unable to send any commands to the server, including fetching new messages, fetching updated message flags, updating message flags, and expunging messages. This state persists indefinitely until and unless the IDLE connection dies too, at which time Akonadi then initiates a new connection. There should be no need to maintain two simultaneous connections in the first place, as the IDLE command can be aborted. Using a single connection both for idling and for other commands would almost certainly fix this bug "for free."
Thank you for reporting this issue in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the issue with a recent software version? If you can reproduce the issue, please change the status to "REPORTED" when replying. Thank you!
I don't use Akonadi anymore. I switched to a mail client designed for IMAP (Trojitá).
