ROCKLIFFE PROVIDES CONTINUITY FOR EUDORA WORLDMAIL CUSTOMERS

Campbell, CA -January 16, 2007 - Rockliffe, the leading developer of high quality email server software for service providers and businesses, today announced that the Eudora® WorldMail® server will continue to be developed as "Rockliffe MailSite." Customers who wish to continue to use the WorldMail server software can easily transition to MailSite SE from Rockliffe. Since WorldMail 3 and 4 are built on the MailSite code base, the upgrade process is simply a matter of running the Rockliffe MailSite installer.

This upgrade path is natural for Eudora WorldMail customers since WorldMail versions 3 and 4 were licensed from Rockliffe and are based on the same code base as Rockliffe MailSite versions 6 and 7. Migration from Eudora WorldMail to Rockliffe MailSite will be a seamless transition because WorldMail is a rebranded version of MailSite SE and thus both products use exactly the same file formats.

"It has been a real pleasure working with the Eudora Products Group to create and enhance the WorldMail server over the past couple of years," said John Davies, president and CEO of Rockliffe. "We have been assisting the Eudora Products Group to make the transition to Rockliffe MailSite as smooth as possible. We are looking forward to working with all of the WorldMail customers and have some very attractive upgrade packages for them. We are offering a 10 percent discount on all WorldMail upgrades and our sales and support staff is standing by to help."
