well, as you are one of the core developers i am sure you know best  
how to enhance the functions

thanks, i think i am now getting closer to understanding things! ;-)

in case some one is interested here is my solution:
first the scenario:

we have one horde system running and two different servers which the  
user can choose on the login page: a linux imap server and a ms  
exchange. to speed up things a bit we are using to local (on the  
horde-server) running imapproxies, the one who is listening on port  
8143 forwards requests to the linux imap server, the one on port 9143  
to the exchange. as the exchange does not support procmail we have to  
distinguish between the two depending on the server chosen by the user  
on login.

so thats what i have now in ingo/config/backends.php

<?php
if ($GLOBALS['_SESSION']['imp']['port'] == 8143) {
/* configuration for imap server -> procmail */
   $backends['procmail'] = array(
     'driver' => 'vfs',
     'preferred' => '',
     'hordeauth' => true,
     'params' => array(
         'hostspec' => 'imapserv.biochem.mpg.de',
         'filename' => '.procmailrc',
         'port' => 21,
         'vfstype' => 'ftp'
     ),
     'script' => 'procmail',
     'scriptparams' => array(
         'path_style' => 'mbox',
         'variables' => array(
         )
     )
   );
}
else {
/* configuration for exchange server -> filtering by client */
   $backends['imap'] = array(
     'driver' => 'null',
     'preferred' => 'exchange.biochem.mpg.de',
     'hordeauth' => true,
     'params' => array(),
     'script' => 'imap',
     'scriptparams' => array()
   );
}

feel free to optimize that! ;-)

thanks again for all who made suggestions and helped with this!

regards
