Prevention of Outbound Unsolicited Electronic Mail
Keywords:Electronic mail, message systems, unsolicited electronic mail
A novel outbound unsolicited electronic mail prevention solution is presented, which can be used in shared web hosting environments. It combines several new ideas, including the rate of non-existent recipient email addresses, the content of the file which called the mail function and automatic actions after detection of suspicious activity to isolate and block it. A complete solution was designed and implemented, all the algorithms were described and presented in the article. The evaluation was done by testing the efficiency of outbound unsolicited electronic mail detection and the number of incidents blocked.
