MailCAGE Email Scanner

Spam Reduction

The MailCAGE email scanner combines technologies such as grey-listing, header and Bayesian spam analysis, and black lists to help reduce the amount of spam or unwanted emails that your users receive. Spam emails can be automatically deleted or flagged to allow users’ email programs to deal with them appropriately.

Anti-Virus and Phishing Prevention

With support for a variety of anti-virus packages, MailCAGE will also quarantine dangerous emails and disable common attack threats such as ‘spear-phishing’ or obfuscated website addresses.

MailCAGE supports admin configurable white and black lists, allowing you to configure addresses that you always wish to receive email from, and those that you never wish to receive email from.

Outbound Mail Control

In conjunction with the NetCAGE firewall guest, all outbound email from your network can be directed through the MailCAGE, to control which devices on your network are allowed to send email, and alert you if a device suddenly attempts to send very large amounts of email.

Mail Archiving

For sites that require archiving of all email sent and received by the company for regulatory compliance, MailCAGE can copy all inbound and outbound emails to our MailARK guest, which allows emails to be stored, searched and eventually archived to external media.
