[Mailman-Users] strange attachment-behaviour when using headers

[peter pilsl]

I've a list that adds headers to all mails.

Now several user using Outlook and Bat report strange behavior with 
mails with attachments: The received mail then only contains the header 
and the original mailbody is only accessible as text-attachment.

example:
user sends a mail to the list containing a message-body and a 
pdf-attachment.
Users with Outlook and Bat  then gets the mail and only the list-added 
header in the mail. To read the original mail they need to click on the 
attached text-file.

When I look at the mail I see that all parts of the mail are 
mime-encoded and it seems that my thunderbird is smart enough to put 
them together while other mailers are not.

Is there any solution/explanation for this?

I found that while the mailman-header is 7bit-encoded, the original 
mailbody is 8bit encoded and different charsets are used. Can this be a 
problem of different charsets that cannot be handled by great Outlook 
and cool Bat ?


example (first is the header, second the original mail)

----------------

This is a multi-part message in MIME format.

------=_NextPart_000_0004_01C65FC6.F3E285B0
Content-Type: text/plain; charset="us-ascii"
MIME-Version: 1.0
Content-Transfer-Encoding: 7bit

Hallo noch mal!

Los gehts :-)
