said Gene Heskett:

| I just changed kernels on this machine, from 4.9.0.9-rt to 4.9.0.9,
| without the rt.  Kmail always has a cow over to folders indices, so I
| expected to get a message about spam and spam-hold which both get
| touched by external scripts or by me moving messages around, but even if
| a nuke all the index files and then start or restart kmail, it has the
| rebuild done in 15 minutes or so.

remind us whether you're using maildir (good) or mbox (bad). (which 
appraisals i give based on the ability to recover messages in case of a 
problem.)
