This is a proxy to your incoming SMTP server, receiving all e-mails addressed to your domain. If the sender's IP is not blacklisted in DNS-MAPS based blacklists, then the e-mail is forwarded to your SMTP server. Statistical Bayesian DNA fingerprinting, along with dozens of blacklist/white rules, are also be applied to filter spam. An optional anti-virus plug-in is available. End users have Web access to their quarantined e-mails. They can view, delete and force delivery of their own quarantined e-mail without having to ask the system administrators.
