Problem with receiving and sending email with my corporate domain

Hello, I would like your assistance in configuring my corporate email as the emails are not being sent from my corporate email "eladiojimenez@eprotech.net" but instead they are being sent from my email eladiorjb@zohomail. Additionally, I am not receiving anything in the inbox of the corporate email. I have already configured the MX, SPF, and DKIM, but still no luck. I am not sure if I need to wait 24 hours for the changes to take effect... On another note, I had set up a forwarding configuration with Google Sites... I am unsure if that is affecting anything. Please help me send and receive emails from the corporate email.
