[imp] Article : " Preventing Email Abuse through IMP"

[Oberdan Albertoni]

Hello,
I read the article on http://hagenbu.ch/blog/70  but I do not understand
how can set the this :"

Once you turn on the driver, there are two permissions you can set
through the Horde permissions API:

  'imp:max_recipients' => "Maximum Number of Recipients per Message"
  'imp:max_timelimit' => "Maximum Number of Recipients per Time Period"


Where can set these parameters, for example to set max_recipients to 10
email and  max_timelimit to 20 for 1 minute ?

Obe.
