It accepts SMTP connections and forwards the SMTP commands and responses to another SMTP server. The 'DATA' email body is intercepted and filtered before forwarding. . You need to be able to write the filtering scripts that integrate it with your particular needs. If you're looking for something that does virus filtering, take a look at ClamSMTP which behaves similarly and uses a similar code base. . You do not need a local mail-transport-agent installed, since this server can forward to a remote one.
