[Mailman-Users] Encoding scrubbed attachment

[Bausch, Jean]

Hi,

I am running Mailman 2.1.8 on a Solaris system and I have activated 
scrub_nondigest for three lists - but the attachments can only be 
correctly viewed for one of them.

When sending a mail with an attached .jpg, two of the lists 
generate an encoded attachment leading to 
- the display of something like
/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEB
AQEB
AQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQH/2wBDAQEBAQEBAQEBAQEBAQEBAQEB
AQEB
AQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQEBAQH/wAARCAHCAl4D
ASIA
when the URL is used in IE
- the display of a page containing only the URL with Firefox.

The third list stores an attachment which can be correctly viewed with
any browser.


I have compared the stored attachments and found that in the first case
the 
attachment contains only printable text:

           A   Q   E   B   A   Q   E   B   A   Q   E   B  \n   A   Q   E

whereas the same command for the correctly working attachment gives the
following:

 od -xc attachment.jpg | head
0000000    d8ff    e0ff    1000    464a    4649    0100    0001    0100

         001 001 001 001 001 001 001 001 001 001 001 001 001 001 001 001

The .jpg file was the same in all the experiments, and I can't find any
difference in the list configurations which could explain this
behaviour.

The only difference between the lists that I can think of is that the
third
has been created after my update to Mailman 2.1.8, the other two are
much
older.

Thanks for helping,
