Ensure Delivery to Destination Servers

In some cases configuration changes are required to the destination server to ensure the Mail Assure servers can deliver to your destination server without interruption. This includes disabling any spam filtering, and any SPF, DMARC, and any Authentication checks as these checks are already performed by the Mail Assure systems.

Multiple filtering of a message/connection is not advisable or supported. To ensure delivery of legitimate messages, disable all filtering for Mail Assure IP addresses, as the IP address for the source of the message on the secondary filtering will be Mail Assure, not the original sender.
