Rackspace Adds Email Archiving

San Antonio's Rackspace Hosting said earlier this week that it has added a new, business email archiving service called Rackspace Archiving. The firm said the new service, which works with its hosted Microsoft Exchange and Rackspace Email services, will provide unlimited storage and unlimited data retention time on email, and also allow for full searching of email data. The firm said the archiving service will cost $3 per mailbox per month.
