How it Works
The PreciseMail Anti-Spam Gateway SMTP proxy receives email from the Internet
and analyzes the messages for viruses (see Figure 2). If a virus is detected,
the filtering engine can take any number of actions. Messages can be rejected,
discarded, quarantined, or forwarded with the infected body part replaced by
a text message indicating that a virus was found and removed. If no viruses
are found, messages are analyzed for spam content. Spam messages can be rejected,
deleted, quarantined, or tagged for end-user review. Legitimate email is forwarded
to the intended destination.
