This specific issue ("src=cid:par1blahblah at blah.com") appears to be
that the MUA (email client) you use to create the mail is downloading
the externally linked file and attaching it to the mail as part of a
(probably) multipart/related message or message part containing the
HTML with references to the attached content.

Have you changed what you use to post the mail?

If you are adding msg_header or msg_footer to the mail, see

If content filtering is off and you are not adding headers or footers,
Mailman shouldn't be making any changes to the MIME structure of what
you post.
