Email Filtering Software: VisNetic MailPermit

The first email filtering software solution is VisNetic MailPermit. More than just an email filtering software solution, VisNetic MailPermit employs Bayesian email content filtering and rules-based anti-spam technology to score email on the likelihood that it is spam. Email scoring higher than established thresholds is deleted and email scoring lower is subjected to user-defined rules for handling.

Remaining inbound email is then subjected to a one-time verification request sent to the source originating the email. If a person, rather than a computer, is sending the email, he or she completes a simple online confirmation task. Once correctly returned, the person's original mail-and all future mail from that email address-is delivered without delay.

Email Filtering Software: VisNetic MailServer

Deerfield.com's SMTP mail server, VisNetic MailServer, may also be considered an email filtering software solution. A number of organizations have deployed VisNetic MailServer as a gateway to existing mail servers, in order to benefit from its powerful email filtering software functionality. These email filtering software features include:

• The ability to filter on subject, sender, recipient, attachments, message size, IP address and key words.
• Support for regular expressions (regex) in filter rules.
• The ability to apply filters globally or by domain or user.

Combined with VisNetic MailServer's standard relay checking, reverse DNS lookup, MX record verification and RBL checking, this email filtering software functionality provides powerful and highly configurable email filtering capabilities.

Email Filtering Software: VisNetic MailScan

Finally, Deerfield.com's email filtering software suite includes VisNetic MailScan, antivirus protection and email filtering software for use with any SMTP mail server. This email filtering software solution includes the ability to create filters for specific words or phrases, DNS lookup to verify sender's "MX" or "A" record and SMTP server authentication to validate sender's account on sending mail server.
