Q:

Configure SMTP using spring-boot-admin

I like to send notification emails with spring-boot-admin-server. I have configured it as described here: 
http://codecentric.github.io/spring-boot-admin/1.3.0/#mail-notifications
However, I do not know how the SMTP is to be used. I think all of them (gmail, gmx,...) require some sort of authentication, isn't it? How can I provide the authentication? 
Or is the idea that you set up your own SMTP server without any authentication?

A:

In case you are using the spring-boot-starter-mail you can configure the mail sender using the spring.mail.*-properties. Username can be set via spring.mail.username and password via spring.mail.password.
Have a look at the corresponding appendix in spring-boot`s reference guide.
p.s.: The SBA 1.3.0 is totally outdated - you should update!
