2. Once you have determined the "From" address, you must work with your Domain Name Service (DNS) provider to create a Sender Policy Framework (SPF) record. If you do not know who manages the DNS for the domain of the "From" address, please work with the technical staff at the ITC to assist in determining this. Without this step, it is likely that messages will be rejected or marked as spam. The SPF record needs to point to the IP address of the MC mail server. That IP address is 188.8.131.52. Your technical staff can use this web site to generate an SPF record (https://www.spfwizard.net/) and then it can be added to the DNS for the domain of the "From" address. It is also possible that you may need to "Whitelist" 184.108.40.206 as a sender in certain email service configurations.
