Clean Mailboxes: Filter E-Mails for SPAM


A major threat to the internal IT security is based on incoming e-mails. The LiSS filter module provides protection against SPAM-E-Mails and infected E-mails through the integrated Antivirus software.


Combination that leads to success

The e-mail filter is located as an intermediary between the sender and the final destination mail server and monitors all traffic. There are different techniques to use filters that can be combined according to the defined procedures.


Effective filtering methods

There are no restrictions on the number of domains to handle. Only by using the application of greylisting a detection rate of 80 to 90 percent or more is achieved. The continuously updated filter systems take care of the remaining 10-20 percent.
