35. Sending email
The Spring Framework provides an easy abstraction for sending email using the JavaMailSender
interface and Spring Boot provides auto-configuration for it as well as a starter module.

Check the reference documentation for a detailed explanation of how you can use |
If spring.mail.host
and the relevant libraries (as defined by spring-boot-starter-mail
) are available, a default JavaMailSender
is created if none exists. The sender can be further customized by configuration items from the spring.mail
namespace, see the MailProperties
for more details.
In particular, certain default timeout values are infinite and you may want to change that to avoid having a thread blocked by an unresponsive mail server:
spring.mail.properties.mail.smtp.connectiontimeout=5000 spring.mail.properties.mail.smtp.timeout=3000 spring.mail.properties.mail.smtp.writetimeout=5000
