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

See 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
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, as shown in the following example:
spring.mail.properties.mail.smtp.connectiontimeout=5000 spring.mail.properties.mail.smtp.timeout=3000 spring.mail.properties.mail.smtp.writetimeout=5000
