I'm guessing Mailman doesn't recognise the suffixes and that's why it's
serving up
$ curl -sSI
http://lists.gnu.org/archive/html/groff/2012-09/binxPeynNmu6F.bin |
> grep -i '^content-type'
Content-Type: application/octet-stream
$
But you can just wget or save the files from your browser and they're
text; see file(1).
Or perhaps Mailman takes the content-type of the MIME parts of the email
and they were application/octet-stream originally?
Cheers, Ralph.
