   Short of fixing the bug yourself, there's probably no way of getting rid   
   of it.  I had been experiencing the message duplication bug as far back   
   as ten years ago.  For the following five or six years, I continued to   
   monitor the progress of the various KMail/Akonadi bug reports on the   
   issue and even helped test various proposed solutions and workarounds.   
   Nobody came up with anything that worked.  I eventually gave up and   
   switched (to Thunderbird at work and Claws Mail at home).  These   
   substitutes can't do everything KMail does, but at least they have no   
   showstopping bugs.  Last I checked, back in 2019 [1], the message   
   duplication bug in KMail was still around.   
      
   If I had complete freedom to do whatever I wanted for several months,   
   I'd learn enough KDE/Qt programming to track down and fix the bug   
   myself.  Or if I had several tens of thousands of euros to spare, I'd   
   hire someone to do this for me.  (Heck, I even offered to chip in what   
   meagre funds I could scrounge up for a bug bounty, but I couldn't get   
   anyone else on board.)
