I am using a gmail email, I have already released the authentication in 2 factors and released the password for app, which I am using in the project. My application.properties, referring to the email properties is like this:
spring.mail.host=smtp.gmail.com
spring.mail.port=587
[email protected]
spring.mail.password=dqcxgtcgxjgewtdgwrew
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
Good morning Wesley I managed to resolve on my local machine by disabling the verification of sending email from PC out, by Avast Antivirus. I was able to find an answer here in stackoverflow.
