Hi Nik,

due to we have also this performance issue (up to 15min to get mails) 
since the upgrade to guam-0.9.2 I think also to owngrade Guam to 0.8.3
Changes in kolab.conf don't help as it helped during the last 
performance issue with guam one year ago.
What is the best way for downgrading guam you suggest?
