Hi @Spectator - hope you're keeping well!
Are you using an outside host for the mail service?
The Ezoic DNS seem to be pointing at stackpath or similar email provider.
If that's still the case, we'd suggest double checking that the Ezoic DNS have the correct values for the mail related services.
If those are the correct values showing, then you most likely would need to get in touch with the mail service provider you're using. As long as the Ezoic DNS are correct, you shouldn't see interference from Ezoic with your email service.
Let us know how we can help you best moving forward!
