There is a new kind of spam that has started appearing in the Ask A Librarian account. The message typically starts like this:

Date: 13 May 2004 11:48:11 -0000
From: MAILER-DAEMON@vm18.variomedia.de
To: refdesk@mailbox.lpl.org
Subject: failure notice

Hi. This is the qmail-send program at vm18.variomedia.de.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.
---------------------------
This is followed by a long string of computer code, which probably contains a virus. Although our e-mail address appears in the header, this message is not in response to anything we sent out. (According to the domain, this message came from Denmark. Actually, it has probably been routed through several e-mail servers to hide the original sender.) It's just spam. Please delete the message.
