SpamFilter ISP 4.0.1.785

It is designed to be a proxy to your incoming SMTP server receiving all e-mails addressed to your domain. To block spam we use our propietary SFBD (SpamFilter Distributed Database), a huge database of spammer's IPs updated in realtime by all SpamFilter installations in the world. A new filter to scan inside embedded images is also included. If the sender's IP is not blacklisted in DNS-MAPS based black lists 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. Examples are country filters, SPF and SURBL filters, remote DNS validation tests. An optional antivirus 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. Version 4.0 features the new greylisting filer and the new SFDC - SpamFilter Distributed Content Database.
