{QUOTE-> Details:

The * Bat! * has special device access bug. If The Bat! is configured to
save attachment apart from message bodies and file has a name of special
device *The *Bat! *will attempt to open special device. This kind of bug
was *described *in *[1]. *This *bug *was probably reintroduced in one of
latest version, because our previous test with this product 6 months ago
failed.

It's *not *clear at that moment if it's possible to write special device
(for example to send attached file to printer or COM port), but this bug
definitely *can *be *used *as *a DoS attack against The Bat!. After this
message *The *Bat! stops receiving of any messages (sometimes absolutely
silent, sometimes warning displayed that file can't be open).
