[Mimedefang] Idea: using action_replace_wiht_url for file transfer

I'm going to jump in here with an alternative suggestion.

The original problem is to send large files to users with limited mail 
file size without having to set up temporary FTP accounts.  The original 
poster also wished to retain the original file name.

Why not use anonymous FTP, but anonymous users can not get a listing of 
the directory.  If the filenames to be transfered are unique enough, you 
could sent the URL as ftp://ftp.domain.org/downloads/uniquefilename.zip. 
If the filenames would be easily guessable, use a URL similar to 
ftp://ftp.domain.org/downloads/randomdirname/simplefilename.zip

Lotus has used this method for years for tech support uploads and 
downloads, so I really can't take credit for it.  Only their internal 
staff had read permission in the directory.
