Upgraded LISTSERV Product Line Released Today, Spotlights Deliverability
with Unique New Assessment Feature

Bethesda, MD (March 2, 2006) -- L-Soft, the company behind LISTSERV - the
original email list management software that celebrates its 20th
anniversary this year - announced today the joint release of LISTSERV 14.5
and LISTSERV Maestro 2.1, a move that enhances the company's product line
with a unique assessment feature to boost deliverability in today's email
environment challenged by spam, phishing and fraud.

Because spam poses an enormous problem for email providers, consumers and
legitimate senders today, and because nearly all spam does not actually
originate from the address it claims to be coming from, many Internet and
email service providers have started to implement authentication and
certification methods in an effort to reject obvious spam while allowing
legitimate email to pass through their systems.

Given the need to control spam without disabling delivery of legitimate,
opt-in email, deliverability is a key priority for email list
administrators, marketers and communicators across the corporate,
government and non-profit sectors. The issue has sparked a recent industry
controversy over fee-based email certification. L-Soft's product line and
corporate stance reflects a strong commitment to opt-in email as the
foundation of deliverability and customer focus.

LISTSERV 14.5 introduces a new Deliverability Assessment interface, a
Web-based center solely dedicated to maximizing deliverability of
legitimate email messages. The feature, which analyzes LISTSERV and DNS
configurations and gives site administrators concrete suggestions on
improving deliverability, helps senders to ensure that opt-in messages
reach the subscribers who have requested them. The assessment encompasses
all three major certification standards that are used by major email
service providers (ESPs), including DomainKeys, Sender Policy Framework
(SPF), Sender ID as well as additional DNS tests. Major ESPs deploy these
standards, with Yahoo! a primary user of DomainKeys, SPF utilized by Gmail,
AOL and Pobox.com and Sender ID used by Microsoft's MSN and Hotmail.

Also released today is LISTSERV Maestro 2.1, the newest version of L-Soft's
sophisticated software solution for database-driven opt-in email
communication and email marketing. Today's release brings additional
deliverability power to users with the introduction of DomainKeys support.
In addition, companies and organizations using LISTSERV Maestro - the only
email list management, tracking and reporting solution built with the power
and flexibility of LISTSERV - can completely customize each page of the Web
interface, so that every subscriber interaction becomes an opportunity for
companies and organizations to connect with subscribers, enhance branding
and convey key messages. Subscriber page customization supports
deliverability because it provides an easy mechanism for subscribers to let
senders know which emails they would like to receive.

Reactions from pre-release customers are positive. Eugene Evans, VP of
Marketing and Business Development for Mythic Entertainment, ranked 90th
fastest growing technology company in North America by Deloitte and Touche
in 2005, stated:

"Regular communication with gamers and fans of Warhammer is a key element
as we ramp up our marketing for Warhammer Online, the new multiplayer
online role- playing game that we will release in 2007. We have
successfully integrated LISTSERV Maestro into those plans, allowing us to
create a seamless interface for fans worldwide to sign up in multiple
languages and manage their own newsletter accounts. LISTSERV Maestro has
successfully delivered hundreds of thousands of email newsletters, enabling
us to clearly communicate our message that this release will be the online
game event of 2007."

LISTSERV Maestro 2.1 also includes a translation tool, which makes it easy
to translate the entire interface, including confirmation and error
messages, into one of 27 chosen languages according to subscribers' needs.
