Version: 2.0.11-1woody8
Severity: normal

If the main body of an email message is base64 encoded rather than
Mailman still appends the footer to the end of the message in plain
text. Besides being wrong, this means that certain antivirus systems
treat the email as being corrupt and bounce it.

It seems that Microsoft Exchange 6.0.6487.1 is particularly prone to
generating such base64 only emails.

Here are some headers from such a message after delivery to a system
that didn't complain about the message:

Version: 2.1

Mailman 2.1 seems to attach the footer as a separate inline
attachment, which solves the cause of this bug. Reopen the bug if you
can reproduce it with a recent Mailman.
