[Dovecot] About using Dovecot indexes with Thunderbird/kmail

I have Dovecot running well on my Mandriva mail hub, handing out IMAP to the household LAN. This is 1.2.15. Eventually I'll upgrade the OS and get 2.x, but this is working fine.

So this question is really about the mail readers I use and how they make use of Dovecot.

I have Thunderbird on my laptop and KMail2 on my desktop.

Dovecot indexes. GOOD! The trouble is that the mail readers want their own indexes :-(

I wish that Thunderbird would NOT index mail on my laptop, but it does. I wish Kmail2 would not use nepomuk/akonadi to index the mail but it does. Why can't they both believe the indexes used by Dovecot?

Is this an unreasonable request?
