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 的工作配置Gmail :

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 两因素身份验证未激活 (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:它看起来像是 可疑连接 .

因此，请检查您帐户上从 google 收到的邮件，以确保连接未被 google 阻止(如果游戏托管在另一个国家/地区而不是您用于手动连接的国家/地区，则会发生这种情况)
