A section on how to define connection/process limits for dovecot has to be added.
(How are the limits calculated?)

Felix, please have a look. It would be nice if we could release the current documentation.

* Connection limit 
  -> Connection limits

* The &ucsUCRV; <envar>mail/dovecot/limits/*</envar> can be set to modify 
  -> The The &ucsUCRV;s <envar>mail/dovecot/limits/*</envar>...

* /etc/init.d/dovecot restart
  -> invoke-rc.d dovecot restart

* the connection between mail/dovecot/limits/default_process_limit=3000 
  and mail/dovecot/limits/auth/client_limit=15000 and the other process limit was
  not clear to me, why auth/client_limit=15000 ...
  please add some more info: 
   * mail/dovecot/limits/default_process_limit applies to all the different 
     process limits. These are ...
     mail/dovecot/limits/auth/client_limit has to be at least as big as the sum
     of all the process limits(?)

* move "High-performance mode" to "UCS performance guide" (and add a link in the 
  manual)

Commit 62609 applies the suggested fixes, moves the chapter on "High-performance mode" to the "UCS performance guide" and explain auth and anvil limits.
