Thanks for this quick reply Glenn,

at first I want to apologize for my first mail,
it has not a good subject; should be "let MailScanner save attachments" 
or so

second I haven't told what I have done so far
I configured fetchmail to fetch the mail from the account :-)
next I configured procmail to process the mail with a python-
script I downloaded from the internet.
This script should extract the attachment from the mail.
But the script has an error.

I have to say that I'm just a "copy'n'past" programmer in python,
so it was not possible for me to eleminate the error in the python-script

So that took me over a day (procmail-receipts are awful).
I had the idea to use MailScanner for the job after giving up on the 

MailScanner idea:
All mail-attachments going to a certain user are stored in the 
To realize that MailScanner "just" has to not-delete the scanned messages.

Is this a possible way?
