[Mailman-Users] Mailman version 2.1.9, content filtering action changed??

[Arthur Hatch]

  Hi,

I need some help with unexplained behaviour changes to the "Content
Filtering" action of a Mailman list, version 2.1.9. The Mailman list
is Xxxxxx, and the unexplained behaviour was first noticed with e-mail
postings on/after Sept.6/07.

The unwelcome changes are that since Sept.6/07, the Content Filtering
configuration is "not" stripping any e-mail message attachments; even
though "multipart" and "image" content are listed. Multipart/mixed, and
multipart/alternative were stripped from e-mail postings before Sept.6/07.
Since Sept.6/07, such offending e-mails are now being Content
filtered/rejected to the listowner. No multipart, or image attachments
are now being removed from the e-mail posting attempts?


Xxxxxx list Content Filtering configuration:

Should Mailman filter the content of list traffic according to the
settings below?

Should Mailman collapse multipart/alternative to its first part content?
(Edit collapse_alternatives)

[ ] No  	[X] Yes

[ ] No  	[X] Yes



Action to take when a message matches the content filtering rules.

I wish to re-establish the past, correct content filtering of:
multipart/mixed
multipart/alternative
image/jpg
image/gif

winmail.dat
htm
html

Since Sept.06/07
There have been  73   postings.
There have been  35   multipart rejections/content filtering without 
stripping.
There have been  36   text/plain postings that were accepted (normal).
There have been  02   "blank", no message body content postings slip 
through.


Can the missing, listed stripping actions be restored to the Content 
Filtering
configuration?

Help and advice appreciated.

    Thank you,
                      Art
