Mailman discussion group footers appear as an attaxched file, not a footer in Outlook


#1

I have a mailman discussion group with some text
in the "Footer added to mail sent to regular list members "

However some mail software does not show that added text. Specifically, Outlook has it as a
file attachment AT000001.txt instead of appending it to the body of the email.

Anyone know how to “fix” this?
