Spring 启动 Sendmail

Question

我无法配置 Spring 和 Sendmail 一起工作。

Spring 边:

pom.xml

  <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-mail</artifactId>
    </dependency>

application.properties

spring.mail.protocol=smtp
spring.mail.host=localhost
spring.mail.port=25
spring.mail.username=
spring.mail.password=
spring.mail.properties.mail.smtp.auth=false
spring.mail.properties.mail.smtp.starttls.enable=false

发送邮件代码（适用于 gmail）

@Async
@Override
public void sendActivationEmail(String username, String activationToken) {
    SimpleMailMessage message = new SimpleMailMessage();
    message.setTo(username);
    message.setSubject(EmailUtils.EMAIL_ACTIVATION_SUBJECT);
    message.setText(String.format(EmailUtils.EMAIL_ACTIVATION_BODY, activationToken));
    this.javaMailSender.send(message);
}

Linux 边:

/etc/mail/access

Connect:localhost.localdomain           RELAY
Connect:localhost                       RELAY
Connect:127.0.0.1                       RELAY

/etc/mail/local-host-names

mydomain.com

/etc/mail/virtusertable

noreply@mydomain.com noreply

（我已经添加 noreply 为用户）

我没有收到任何错误。日志中没有任何内容。也没有发送电子邮件。我该如何全部配置？

Answer 1

某些超时值在 Spring 默认情况下是无限的。尝试按照建议将超时值设置为合理的值in the documentation，看看是否超时。

spring.mail.properties.mail.smtp.connecttimeout=5000
spring.mail.properties.mail.smtp.timeout=3000
spring.mail.properties.mail.smtp.writetimeout=5000

https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-email.html

同时设置发件人地址：

message.setFrom(...);
