I have create a email service to which I have a class attached to create contact record. When I send email from Gmail, redifmail I am able to receive email and contact is created but when I send a email from my personal company email id (firstname.lastname@example.org) with company domain name I am not able to receive email. I have added the my company domain to my email service. When I send a email from my company domain I am getting error message to my email id.
