SV-44042r1_rule Accepted domains must be configured.

Vulnerability discussion

Exchange may be configured to accept email for multiple domain names. This setting identifies the domains for which the server will accept mail. This check verifies the email server is not accepting email for unauthorized domains.

Check content

Obtain the Email Domain Security Plan (EDSP) and locate the 'Accepted Domain' values. Open the Exchange Management Shell and enter the following command: Get-AcceptedDomain If the value for 'AcceptedDomains' is not set to the value in the EDSP, this is a finding.

Fix text

Open the Exchange Management Shell and enter the following command: Set-AcceptedDomain -Identity <'ValueInEDSP'> -MakeDefault $true

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
