[Mailman-Users] Attachments - PDF Issue

[John DeCarlo]

Chris,

Again, changing Scrubber.py will affect all the lists on that server.

Warning aside, I took a look at Scrubber.py.

Look at the function save_attachment().

The line 'ext = guess_extension(ctype, fnext)' tries to guess the proper 
file extension based on the extension of the file name in the message 
(fnext) and the MIME content type (ctype).  The content type is the 
primary determinant.  If guess_extension() doesn't give an answer, the 
if clause just beneath it takes over.

You have several options available, as with any programming change.

1.  Just give every file the extension it had in the message.  To do 
that, change the else: line to:

ext = fnext

2.  Just worry about the .pdf files.  To do that, in front of the else: 
line type in:

elif fnext == '.pdf':
    ext = '.pdf'

(Now I am not 100 percent sure this will work, not being a Python 
programmer, so take it with a grain of salt.)
