Using Active Directory (Exchange) or LDAP to set up valid email addresses

This feature is available on the Basic, Standard, Enterprise and Reseller plans.

If you have a Microsoft Exchange server with Active Directory or an LDAP server, you can use our LDAP user sync tool to automatically setup valid email recipients. To get started, login to your SpamHero account and go to Tools > ldap user sync. Each field on the form has a "quick tip" that will pop-up to assist you in completing each step of the setup.

  • Make sure your Active Directory/LDAP server is online.
  • Make sure your firewall settings are allowing the SpamHero IPs. See: Current List of SpamHero IPsOnce you have LDAP syncs working, you can view a history of LDAP syncs that have occurred using the history tab:
