ITFlow lock key in /tmp is not removed.

Seems to me access to IMAP is just fine, and all unread messages are switched to read, and the first email creates a ticket.
Then it tries to move the first imported email to the "itflow" folder, but fails to do that, and switch all read emails back to unread.

Does the emailparser create ITFlow folder in the IMAP account, or do I do that manually? If so, any particular format? "ITFLOW" , "itflow"? In the root folder?

Got the exact same error on Ubuntu 22.04 / PHP to v.8.3 (upgraded), hence decided to try a new install.

Any help highly appreciated 😊
