Thank you very much for your suggestion. I gave 'detach' a try, and saw that 
you contributed to it :)

It does exactly what I need. I set it up as a transport for postfix. The 
script that gets called by postfix also takes care about delivery (pipe 
through dovecot's 'deliver' after the detaching is finished, or, in case of 
an error during the detachment process, pipe the original message (including 
attachments) through 'deliver'. I didn't want to install procmail, because I 
need dovecot's sieve plugin for all other filtering needs...

I've got one problem though (which I reported to Ryan Hamilton): detach 
doesn't handle attachments with filenames that contain non-ASCII characters 
well. I don't know anything about perl, so I didn't dig deeper yet... Would 
you perhaps be interested in looking into the issue?

For me it's just about getting those attachments to some SAMBA share - the 
rest of the mail should stay as it was.

Thanks again for that hint,
Patrick.
