As someone else pointed out, there are a number of valid attachments

This probably wouldn't help. A lot of virus set them semi-randomly, as
they are ignored by the Windows family of operating systems, which
relies on ``magic numbers'' to indentify file types.

PS: I recommend CC'ing such emails to listmaster@lists.debian.org if you
wish to get a reply from us. I only saw this email by chance when I was
manually cleaning the queue from said viruses.

PPS: and I'm not subscribed to this list, so please CC me as well. =-)
