dmarc

This is a quick how-to on setting up the record. If you want a more in-depth one, there are many available elsewhere. So for now, here it is

Login into your Email Server

Create a new email address. Something like dns@tacticalware.com

Next, Login into your DNS Provider
Ex – Network Solutions, Hostgator, ENOM

Navigate to the area to Manage DNS records

Create a TXT record

Name will be
_dmarc

Value will be:
v=DMARC1; p=reject; rua=mailto:dns@tacticalware.com; ruf=mailto:dns@tacticalware.com; fo=1;

Make sure you change dns@tacticalware.com to whatever the email address is that you created in the first step

Save the record

Go to MXToolbox.com and enter your domain name

You should see a green checkmark next to DMARC
