I don't know how is that possible because data are correct and I can log with them to my account on and other properties are also correct, i took them from official website : https://getmailspring.com/setup/access-ovh-net-via-imap-smtp So everything should be correct. I can logi in here with no problem: https://pro2.mail.ovh.net/owa/#path=/mail

I am using spring boot and JavaMailSender and Java.

How to solve it?

spring.mail.username=XXXXXX
spring.mail.password=XXXXXX
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
