Lightweight Linux e-mail platforms pack a punch
E-mail is a killer application. Your organization can become immobilized when messages dont flow. Servers need to be restarted for security patches. Whole infrastructures must be taken offline for costly hardware upgrades that provide redundancy or satisfy mailboxes bloated with duplicate attachments.
One way to break this never-ending routine is to go the Linux route for e-mail and calendaring. Before you dismiss this as totally unrealistic, given your significant investment in Microsoft Exchange, IBM Lotus Notes/Domino, or Novell GroupWise, take some time to consider two strong Linux e-mail and calendar solutions: Scalix 10 and Zimbra Collaboration Suite 3.0.
