[Evolution] Maildir update frequency.

[O Polite <m2 plusseven com>]

I just moved from mbox to maildir. Now I do all retrieval and filtering
with fetchmail / procmail. I should have done this a long time ago. 

One thing though. Evolution's updating of the folder contents is a bit
strange. It updates the contents when I leave a folder and not when I
enter it.

Any way to control this?
