I have got my mail to discuss from slim devices in 2 versions, I normally
get one.

One is without any files sent in the mail

The other one sent with files in the mail. This has information:

Received: from windermere.tfnet.ca (ns2.torfree.net [])

by lists.slimdevices.com (8.12.9/8.12.6) with ESMTP id

for <discuss (AT) lists (DOT) slimdevices.com>;

Since there is a virus which sends mails including viruses from wellknown
mailadresses, I have a question about this.

Could this be such a one?
