Solutions for Inbound Protection
The ultimate goal of Inbound Protection is to provide clean and authenticated messaging. Once a message has passed
gateway inspection, it is verified and filtered prior to mail store handling and inbox delivery.
The first step of inbound protection is authenticating the legitimacy of a message. Sendmail inbound protection includes integration with all the leading authentication mechanisms, including the only Internet standard for authentication, DomainKeys Identified Mail (DKIM). The remaining legitimate messages are then filtered and sorted to remove spam viruses and other unwanted content. Sendmail provides multiple filtering technologies for spam and viruses.
The following key features for Inbound Protection are available with Sendmail appliances and software to deliver clean and authenticated messaging.
