I watch this since this morning. It made KMail unusable right now, so 
using not-so-good web interface right now... I didn't do any change in 
configuration or upgrade. I'm using KDE PIM 18.12.

I don't see such problems. I use most of filters on the IMAP server side 
and when I search within even large folder (well, for me up to ~10-20 
000 mails), it is basically instant.

Few of this issues I also saw recently. Sometimes it happened that I 
manually moved mail to some folder, it was moved (well, rather copied), 
but it stayed in the original folder. Bit annoying.
Is there way how to clear Akonadi cache for all 
folders/accounts/resources in once?

I use Akonadi-ews and it works perfectly. Well, if You believe Exchange 
could work at all. ;-)

I don't remember when my KMail crashed last time.

I like Evolution, but KMail has so much more features...

KMail does sometimes... :-(

I has been running akonadictl fsck for several hours already (! it has 
never happened before) and now it reports tones of messages like
Cleaning up missing external file: 
/home/vojta/.local/share/akonadi/file_db_data/65/617965_r0 for item: 
220946 on part: 617965
I wonder how it will look on my other computer (both running openSUSE 

I don't have much annoying issues with KMail, for me it's still the best 
e-mail client. I don't wish to leave it. :-)
So big thanks to all developers.
