Hi,

We use postfix in front of our local email servers where 80% is based on 
exchange. We have around
25000 users/distlist/emaillist

We would like to implement a system where all email addresses are known and 
which server will handle it.
Because this is a heterogeneous environment the system should contain all valid 
email addresses and the 
name of destination server for this.  I can't use AD for this. I can't use 
transport maps to do this.

Lets assume I have this information in an Ldap server:

        email address        Source Route
           -------------        --------------
        maile...@xxx.dk xxx.sdu.dk

When I receive an email this is what we do now:

      --> MTA-IN  --> AMAVISD-NEW  --> MTA-OUT --> DEST SERVER


I would like to implement this after the MTA-IN but I'm not sure what to use.
Have looked into the content filter mechanisms but I don't think this is the 
way to go.
Maybe implement some kind of policy daemon ?

Can anyone point me into the right direction so I'm sure that the address 
mai...@xxx.dk is sent to
the server xxx.sdu.dk ?
