I performed the tests with a test email, I was able to send the email through my application.

When I changed to the production email, the error appeared "Failed messages: com.sun.mail.smtp.SMTPSendFailedException: 553 Relaying disallowed as aneto7@zohomail.com"

I would like help to resolve this issue.

spring.mail.host=smtp.zoho.com
