I get an error each time that I submit a CF7 form to an email address with the same domain as the domain (website) that the Forms are being submitted from.
For example, I have http://www.test123.com web site with a CF7 form. The CF7 form is setup to send TO email@example.com. When I submit the form I get an error [red box]. However I change the TO address to firstname.lastname@example.org and it goes through. The email alias is on the same hosted email server and it goes to the same mailbox.
Is this because the email that is being sent TO is the same as the domain name of the website? Are there any logs or way to find out. I have tried different email addresses on the same email server and the same problem.
