When people outside your organisation contribute messages to an Exchange distribution group, this can cause DMARC problems that result in mail being bounced.
Your Exchange server will send out the mail from its original sender, but because that sender’s address is in a different domain to yours, the emails sent to distribution group members can be detected as spoofed if the sender’s domain has a DMARC policy.
Our DMARC Compliance Agent solves this problem.
The DMARC Compliance Agent is sensitive to the version of Exchange server being used. Currently Exchange 2013 and 2016 are supported. Make sure you install the version that matches your Exchange server. This licence allows you to install the DMARC Compliance Agent on multiple servers in a single Active Directory forest.
To install the transport agent, log in to a Mailbox role Exchange server using an account with administrative rights in Exchange and run the .msi file.
