Trouble adding Email Delivery SMTP details for Gmail
I'm having trouble get OCI's SMTP server to work in Gmail as I would like to use Gmail to send emails with my own domain. I believe I've configured email delivery correctly, as I've been able to send emails using Apple's Mail app, and also tested it with https://www.gmass.co/smtp-test. However, whenever I try to configure Gmail, it keeps giving me this error.
Oops, we weren't able to finish. Please verify that you have entered the exact settings provided by your other email service. Contact your other email administrator for further details.
I've made sure to use port 587 with TLS, and I've tried regenerating the SMTP credentials multiple times with different users. I've also done the same config with AWS SES and everything went smoothly. I have no idea what I am doing wrongly so any help on this would be greatly appreciated!
