Okay, nice idea, I added that, BUT:

When delivering such an e-mail to the host, the pipe_transport is obvious-
ly not used. See log:

One mail with "wrong" subject:

| 2006-10-23 11:49:08 1GbwQe-0001dP-A5 <= thomas@??? H=mail03.noris.net 
|    [62.128.1.223] P=esmtp S=3086 id=20061023094743.GI12225@??? 
|    T="test"
| 2006-10-23 11:49:08 1GbwQe-0001dP-A5 => thomas <thomas@???> R=localuser 
|   T=local_delivery
| 2006-10-23 11:49:08 1GbwQe-0001dP-A5 Completed


And one with the right one:

| 2006-10-23 11:49:26 1GbwQw-0001dY-7k <= thomas@??? H=mail03.noris.net 
|    [62.128.1.223] P=esmtp S=3106 id=20061023094801.GJ12225@??? 
|    T="blubberdiblubb"
| 2006-10-23 11:49:26 1GbwQw-0001dY-7k => thomas <thomas@???> R=localuser 
|    T=local_delivery
| 2006-10-23 11:49:26 1GbwQw-0001dY-7k Completed


The transport "local_delivery" is used, although my test router is the first
one in the main configuration file.

The filter itself should work, as testing reports:

Still in need of help :-)
