This Exchange Server plug-in utilizes familiar technologies from SmartPOP2Exchange to effectively filter spam with SpamAssassin, scan for viruses, and backup email.

The spam filter is top-notch and reliable, as it utilizes SpamAssassin with Bayes filters and the ability to learn spam and ham manually. Additionally, the blacklist and whitelist (for e-mail addresses) are integrated into the software.
One of the best features of Exchange Server Toolbox is the backup service that allows you to write any incoming or outgoing e-mail message into a specified folder. This feature saves mail and easily meets legal requirements for the archiving of business e-mail.
The software is compatible with almost all virus scanner programs, allowing you to use your favorite virus scanner for checking e-mails and discovering and deleting infected e-mails. Plus, the software comes with a separate, extended Windows event log.
Finally, the user manual and help file are included in the installation, making it easy to learn how to use the software. Overall, Exchange Server Toolbox is a great software solution to keep your mail safe and spam-free.
