Question

我在Scala中有一个应用程序，我使用play mailer 6.0.1向大约20-30人发送电子邮件。我在后端使用akka来安排邮件在特定时间（周二恰好是上午10点），并且一个接一个地向大约20-30个人发送邮件。除了1或2之外，几乎所有的邮件都完美无缺。这里是我得到的错误信息：

我有以下配置：

play.mailer {
  host = "smtp.gmail.com"
  port=587
  ssl=no
  tls=yes
  user = "USERNAME@EMAIL.COM"
  password = "PASSWORD"
  debug = no
  timeout = 60000
  connectiontimeout = 60000
  mock = false
}

对上述错误的任何见解都会非常有帮助。请务必询问您认为必要的任何内容，以便了解上述错误的根源。

有些电子邮件没有使用播放邮件插件发送
