Linux Journal has an interesting article on Caldera's Volution Messaging Server, a Microsoft Exchange replacement for the SMB market. “Caldera's VARs, picked up with the acquisition of SCO last year, had a problem: Microsoft Exchange. Microsoft's notoriously complex mail server package was impractical for small and mid-sized businesses, but in order to sell those customers on a replacement, VARs had to offer compatibility with the shared address books and calendars that are part of the popular mail client Microsoft Outlook. “
“The solution is Caldera's Volution Messaging Server, which combines SMTP, IMAP, POP and web mail in a single, web-administered package licensed for $28 per seat. “Users don't know it's not Microsoft Exchange”, Imershein said. And from the administrator's point of view, the skills to be mastered are simpler than those in the thick MS Exchange manuals. “ “Under the hood, Volution incorporates three key open-source packages: OpenLDAP, the Postfix MTA, and Cyrus for IMAP and POP. Caldera's additions, licensed under viewable source terms, include the web-based admin tools and a flexible alias management system. “
