SOFTWARE/OS VERSIONS
KDE neon 6.0 (regular ubuntu 22.04 with added neon repository)
KDE Plasma Version: 6.0.0 
KDE Frameworks Version: 6.0.1
Qt Version: 6.6.2

ADDITIONAL INFORMATION
If akonadi is first stopped with “akonadictl stop” it starts ok.
If the “Server Supports Sieve” option is disabled it also starts ok.
If enabling sieve support after starting up it will allow me to edit my sieve scripts.
Stopping akonadi does not result in successfull start in case kmail is started through kontact.
