[Mailman-Users] Attachment problems

[ichankl at iprimus.com.au]

Hi,
Mailman is the default mailing list application offered by my web hosting
company through its web-based control panel interface.

I created a mailing list but we have been experiencing problems with attachments.
Whenever an email message with an attachment is sent to the mailing list,
the email message gets through to all recipients but the attachment (whether
a Word document, image, PDF or Excel file etc) will always be scrubbed and
shows up as a unopenable .dat file. The attachment is also scrubbed at the
list archives so there's no way list members can view the attachment. 

Does anyone have any advice how to get around this problem, so that attachments
can pass through successfully in the original message to all recipients?

I have the content filtering option set to "No", and have not placed any
limits on message size.

Thanks
Iris Chan
