getting pop3 emails filtered through ispconfig install

[Ovidiu]

sorry for the strange title of the post, I couldn't quite find a better one.
What I mean is this: I am hosting a domain where my primary email address is on, on my root server with an ispconfig installation. now I'd like to get alle my other mail accounts onto this system. so I have a single web interface and all my accounts like those on hotmails, etc. get filtered and scanned too. BUT if I use squirrelmail and its fetchmail plugin those mails will not get scanned and filtered, they simply land inside my Inbox and thats it...

for the moment I have all my other accounts forward me copies of all messages, but wouldn't it be more elegant if I could fetch them? what do you think? anyone doing something similar like this or am I just not making any sense?
