3.5 Set 'Enable automatic replies to remote domains' to 'False'

Information

You can use this setting to determine if the server automatically replies to remote domains.

Rationale:

Attackers can use automated messages to determine whether a user account is active, in the office, traveling, and so on. An attacker might use this information to conduct other types of attacks.

Solution

To implement the recommended state, execute the following PowerShell cmdlet:

Set-RemoteDomain -Identity Contoso -AutoReplyEnabled $false
