Mailtrust Announces Hosted Exchange 2007 Offering For Resellers, Enhancements To Control Panel

BLACKSBURG, Va.--(BUSINESS WIRE)--Mailtrust™, a leading business-class email specialist and a division of Rackspace® Hosting (NYSE: RAX - News), today announced that their 450-plus resellers will be able to offer their customers Hosted Exchange 2007. Previously, resellers could only offer Managed Exchange 2003 or Noteworthy®, Mailtrust's premier web-based business-class email platform. The ability to offer Hosted Exchange 2007 is due in large part to the newly redesigned Control Panel for Mailtrust users.

Mailtrust's Control Panel is an easy-to-use interface for customers needing to administer to their email domain and with the new enhanced version, it's even easier, faster, and more flexible. Customers can log in and with the click of a few buttons, add or remove both Exchange and Noteworthy mailboxes in the same interface and domain. This is the next step for Mailtrust to offer a seamless hybrid product for customers wanting to use both Noteworthy and Hosted Exchange.

"Mailtrust has more than 450 resellers offering Mailtrust's superior messaging services to end customers. Theses resellers are a vital aspect of our business model, accounting for more than 545,000 Noteworthy mailboxes on 113,000 domains," said Adam Williams, manager of reseller sales, Mailtrust. "In return, our resellers benefit from our 100 percent uptime guarantees and industry-leading support, as well as a customizable business email solution to sell to their customers, which can save them heartache and money."

Hosted Exchange 2007 offers significant upgrades that include larger two-gigabyte mailboxes, larger public folders, web access tools with AJAX enabled interface, and best of all can be fully synchronized with Noteworthy. With Mailtrust's hybrid solution of Hosted Exchange and Noteworthy, Exchange users will be able to fully utilize the Exchange environment, while Noteworthy users enjoy a business-class email suite well equipped with everything from webmail to mobile access. Both come with world-class spam & virus protection, a 100 percent uptime guarantee and 24x7x365 support. Best of all, both platforms can be administered from one central Control Panel.

"With the Mailtrust Hybrid solution, the demands for Microsoft Exchange, shared calendaring, public folders and mobile interface can be satisfied along side users just needing a simple mailbox with POP3/IMAP4/Webmail over SSL," said Joe Welke, Technical Director, KD Interactive. "Mailtrust allows us to resell a wide range of email and wireless devices and services, allowing our customers increased flexibility in tailoring their services to meet changing needs on a per-user basis in real-time all the while saving them time, resources and money."
