Delivering to subfolders with address extensions

[Chris Hastie]

Hi

I'm looking at migrating an existing postfix + cyrus mail system to
Kolab 2.2.1. The existing system makes extensive use of address
extensions to deliver mail to subfolders, ie

user+subfolder at domain.com

is delivered into subfolder beneath user's Inbox. This was fairly easy
to achieve with Cyrus's "deliver" command, with this in postfix's master.cf:

cyrus     unix  -       n       n       -       -       pipe
  user=cyrus argv=/usr/local/cyrus/bin/deliver -e -r ${sender}
 -a ${user} -m ${extension} ${user}

Is there any way to mimic such behaviour in Kolab? An awful lot of my
existing routing arrangements depend on this.
