FOR IMMEDIATE RELEASE

Denes v1.0.0b06 Released by Deep Sky Technologies, Inc.

EIMS Filter for DNS Lookups Using Custom Rules

Vero Beach, FL - Monday, November 15th, 2004: Deep Sky Technologies,
Inc., today announced the release of Denes v1.0.0b06 for Mac OS 9 and
Mac OS X. Denes is an EIMS filter for performing DNS lookups using
custom rules and criteria. This first fully public beta release of
Denes is open to all owners of EIMS and EIMS X and is available for
use through the month of November, 2004.

Denes is an EIMS filter for taking actions on email based on DNS
lookups using custom rules and criteria. Denes allows email to be
accepted or denied based on DNS lookups, making full support for DNS
based blacks list and white lists available in a single filter; there
is even a simple test mode to log DNS lookups without actually denying
or accepting email.

The most convenient feature of the Denes rules document is that it
dynamically reloads after any changes made in it. This means, Denes
rules can be added, modified, and/or deleted without having to quit
EIMS and launch it again. When any changes to the rules document are
detected, Denes will reload the rules for subsequent use in the
filter.
