Been there, done that, same result. In fact, the whole indexing failed much 
more miserable before I tuned the mysql config to some degree, due to timeouts 
(which is okay, given my admittedly pathologic case).

Yes, I hope so as well. But it's still indexing (since Thursday...), and 
crashed the system hard at least once.

Well, that's not a problem here, since I don't use any local filters, all done 
with sieve on the server, of course.

Will try Postgres, then. When throwing away the whole akonadi folder, there's 
a real PITA: it enumerates all IMAP folders, resulting in a fully mixed up 
special folders setup (Sent, Drafts, Templates, Trash) for all accounts :-(

That's a major flaw of kmail since ever... Cannot remember kmail 1 behavior 
exactly, though. ;-)

Pete
