This was at some point a quoted-printable encoding. I don't know where
the '>' at the end of the first line came from, but in
quoted-printable speak the '=' at the end of the first line of

Url : <http://www.mn.us/pipermail/listname/attachments/20050901/2d8=
eb35e/OfficialnoticeSpamFilteringUpdate09030.pdf 

means "there is really no line-break here - join this line to the next".

I've looked at Mailman/Handlers/Scrubber.py, and it doesn't put angle
brackets ('<', '>') around the urls. I don't know where they are
coming from, but I don't think Mailman is doing it.

Likewise, Scrubber.py does not produce a quoted-printable encoded
message. It produces a message with Content-Transfer-Encoding: 8bit.

So it looks like somewhere in the outgoing MTA path, an MTA is
converting 8bit to quoted-printable which is changing

to

Url : http://www.mn.us/pipermail/listname/attachments/20050901/2d8=
eb35e/OfficialnoticeSpamFilteringUpdate09030.pdf

and then somewhere further along, something is not correctly
interpreting the quoted-printable encoding - perhaps the thing which
is putting the angle brackets around the
http://www.mn.us/pipermail/listname/attachments/20050901/2d8= part.
