Mirapoint includes installation support in its pricing, although the wizard-based installation process is clean and clear
enough that help may not be necessary for experienced administrators.
The Message Server includes an e-mail server with POP and IMAP functionality, and it supports Outlook mail clients, as well
as other standard clients, such as Eudora and Thunderbird. Users can also access their e-mail, calendars, and address books
through a Web portal. The Message Server can synchronize with corporate directories, including LDAP and Active Directory.
The Message Server offers a flexible and scalable e-mail solution and an excellent user experience. It offers shared calendaring,
auto-addressing through a standard company address book, as well as individual address books, shared mail folders, and the
ability to allow users to search for false positives and maintain their own whitelists and blacklists. Sophos anti-virus filtering
is maintained for all whitelisted messages, as you would expect.
The system includes a nicely integrated backup system that allows selective restores of individual mailboxes. Like IronPort’s
appliance, the Message Server supports “n + 1” clustering, so it is also highly scalable.
Although initial anti-spam performance included a relatively high number of false positives compared with the IronPort, whitelisting
the senders was easy, and within a few days, the number of false positives dropped. After five days of testing, the Mirapoint
snared only two additional false positives, both bulk messages.
Security features are strong, with content management, virus protection, directory harvest attack protection, and an HTTP
proxy that brings additional security to Web access. Message Server also validates recipients against a directory to thwart
directory harvest attempts.
Creating policies for filtering mail based on content or attachments is simple and straightforward, and the tools are powerful.
For example, “wiretaps” make it easy to monitor all e-mail coming to or from any address. Anything that the content filters
catch is quarantined for review by the appropriate manager.
Either of these appliances will provide excellent e-mail security for companies of pretty much any size. The Mirapoint Message
Server combines an easily managed and capable e-mail/calendar server with excellent e-mail security features. For admins who
already have an e-mail server, the RazorGate series provides the same set of excellent security features without the mail
server.
The IronPort C-Series delivers excellent anti-spam results right out of the box, with no tuning necessary. It also provides
great monitoring and troubleshooting tools. The Mirapoint system needed tuning to boost accuracy and weed out false positives,
but after a couple weeks of breaking in, it should achieve similar levels of performance.
