Hi,

  I mitigated (or solved?) the issue by editing master.cf.template and 
changing this line:

kolabmailboxfilter     unix  -       n       n       -      -        pipe 
user=kolab-n null_sender= argv=/kolab/bin/php

to:

kolabmailboxfilter     unix  -       n       n       -       2       pipe 
user=kolab-n null_sender= argv=/kolab/bin/php


Given that amavisd gets only 2 emails at a time, I thought 2 was a good place 
to start. 

Thanks,
