Right, but should Horde be checking for new mail when I go into Turba, 
Nag, etc.. ? As far as I can tell every link I click on in Horde causes 
an imap connection to be made. And this only happens when hordeauth=true 
is used in IMP. If hordeauth=false then the imap connections only start 
when you actually go into IMP.

I have not checked to see if the same thing happens if Horde is 
configured to use IMP for authentication.
