Thanks to Larry Nguyen for
this link.
This program is open to all and runs from 25 June through 30
July.
Join the beta program and discussion group by completing a form
at the HP Web site. Once you have agreed to the conditions of the
program you will then be able to download the OpenMail server
installation image for RedHat Linux 6.0, the OpenMail MAPI Service
Provider for the Microsoft Outlook client, and the OpenMail Motif
Client for Linux (OMGUI). You will also be able to access the
discussion group for support issues.
Support is through a discussion group and is on a “best effort”
basis. You may join only the discussion group if you do not want to
download the software.
