EX13-MB-000245 - Exchange must have antispam filtering installed.

Information

Originators of spam messages are constantly changing their techniques in order to defeat spam countermeasures; therefore, spam software must be constantly updated to address the changing threat. A manual update procedure is labor intensive and does not scale well in an enterprise environment. This risk may be mitigated by using an automatic update capability. Spam protection mechanisms include, for example, signature definitions, rule sets, and algorithms.

Exchange 2013 provides both antispam and antimalware protection out of the box. The Exchange 2013 antispam and antimalware product capabilities are limited but still provide some protection.

Solution

Update the EDSP.

Install the AntiSpam module.

Open the Exchange Management Shell and enter the following command:

& $env:ExchangeInstallPath\Scripts\Install-AntiSpamAgents.ps1
