MailScanner 4.78.17 doesn't detect viruses, have checked tmp

I've got a whole rack full of virtualisation hardware available here,
thanks anyway.
If you want to make a small donation, there are quite a few things on my
amazon.co.uk wishlist, any of which would be very much appreciated! The
side-cutters would be most appreciated at the moment, but anything you
like the price/look of would go down well :-)
Thanks,
Jules.
