将电子邮件发送到以下服务器失败:smtp.gmail.com:25

Question

当我尝试从scala Playmework发送邮件时,我收到了以下错误,

如何解决这个错误？

SignUpProcess.scala

private def sendEmail(subject: String, recipient: String, bodyString:Html) {

        import scala.concurrent.duration._
        import play.api.libs.concurrent.Execution.Implicits._

        Akka.system.scheduler.scheduleOnce(1 seconds) {
          val mail = use[MailerPlugin].email
          mail.setSubject(subject)
          mail.addRecipient(recipient)
          mail.addFrom("innodeagcm@gmail.com")
          println(bodyString)


          mail.sendHtml(bodyString.toString)
        }
}

application.conf

smtp.host = smtp.gmail.com
smtp.port = 465
smtp.ssl = true
smtp.tls = no
smtp.user = "companymail@gmail.com"
smtp.password = "mypassword"

Answer 1

1. 这是GMail的工作配置:

smtp.host=smtp.gmail.com
smtp.port=587
smtp.ssl=yes
smtp.user="me@gmail.com"
smtp.password="myPassword"

您必须使用端口587(因此激活SSL)

2.还要确保未激活双因素身份验证(否则您必须生成新的应用程序密码)

3.连接失败的另一个原因是:它看起来像是一个可疑的连接.

因此,请检查从您的帐户收到的来自谷歌的邮件,以确保谷歌没有阻止该连接(如果播放是在另一个国家/地区托管,而不是您手动连接的国家/地区)

Answer 2

smtp:port = 587对我不起作用.但是465端口为我工作.

并打开谷歌不太安全的应用程序设置

smtp.host=smtp.gmail.com
smtp.port=465
smtp.ssl=true

Answer 3

您应该首先在 Google 中启用安全性较低的应用程序的访问权限，如上述答案所示。现在将端口更改为 465 并设置 ssl=true。或者您可以设置 port=587 和 tls=true。这是因为根据官方文档，端口 465 用于 SSL，端口 587 用于 TLS。

端口=465
ssl=true

**注意 port=587 和 ssl=true 将不起作用
