Right, identifying that is going to be the key.

I'm obviously not seeing that in my use either, but that's all IMAP/Sieve as 
well. The only time I had to do some database surgery in the past ~10 years or 
so was when we hit the MariaDB <-> Qt date/time incompatibility issue, which 
was caught and fixed upstream before it hit the majority of users thanks to 
people using bleeding edge in production. Most of my Akonadi setups are by now 
probably older than the machines they are running on.
