Email Send exception while calling the /registration API

[apeksha.barhanpur]

Hi,

We are calling the /api/user/registration API to create and register a new user. Our requirement is that we want to send an email verification first to the user, only after the user clicks on the link and verifies the email then we would like the user to be verified in FusioanAuth.

Based on the API documentation it states that when we make a request to this API and if the "skipVerification" is set to default with is "false" it should send an email verification to the newly created user. And then the user should get an email.

Though the call is successful we are getting the following error within the event logs while sending the email.

Async Email Send exception occurred.

Template Id: 0e107c44-a3de-4607-b51c-cd797463ce3a
Template Name: [FusionAuth Default] Email Verification
Tenant Id: 07448f27-ca36-9612-8b9a-bce2e7137351
Addressed to: apekshagb@gmail.com

Cause:
javax.mail.MessagingException : Message: Could not connect to SMTP host: 127.0.0.1, port: 1025

I did try to use an external SMTP server as mailcatcher but that didn't work either. Are we missing any configuration or we need to call a different API?
