spring.mail.host = smtp.zoho.com
spring.mail.port = 587
spring.mail.username= emialid
spring.mail.password = password
spring.mail.properties.mail.smtp.auth = true
spring.mail.properties.mail.smtp.starttls.enable=true
I am getting following error:

nested exception is:

Answer 1

You have to mention setFrom() with an email address that you use as the username for auth.
Make sure that the username and the from address are same.
