Can't receive mail from a web form
If you have a form (using PHP/ASP/etc) on your website that is configured to send a message to your G Suite email account, but you never receive mail from your website's form, please perform the following tests:
- Send a message to your G Suite email account from a non-G Suite personal email account.
- Modify the form to send mail to your Gmail account, or another non-G Suite personal email account.
When someone submits the form on your website, the mail agent recognizes your domain name and concludes that it should be sending mail to itself. The mail agent will attempt to deliver the message locally.
To resolve this issue, notify the mail agent running on the server that hosts your website that it is not also responsible for handling mail for your domain. Contact your web host for specific instructions. If you host your own website, contact the support team for your mail server software.
