Verify your domain DNS settings
Your website and email are identified by a domain name. behind this is an IP address.
The IP identifies through the system where the domain is situated. I have some hints below that can be used to verify that your domain is setup correctly.
Some security mail settings such as DMARC do have a bearing on the security of your email, in our opinion you should have this setup.
I use mxtoolbox.com to test my domains.
Step 1 is to test the MX settings of your domain. For our example below we will test the domain "fife.co.uk"

Now we run the SMTP test to verify sending to the domain.

Next we review trying to send through the domain from an external source. "Relay Access Denied" is good outcome.
