Google Instance 使用 GSuite/Gmail 发送邮件

Question

使用 GCE 实例从 wordpress bitnami 构建发送邮件时遇到问题。

我知道正常的 SMTP 端口在 GCE 上是关闭的，但我使用了 gmail API，与以下创建 API 连接的指南非常相似。 http://www.wpbeginner.com/plugins/how-to-send-email-in-wordpress-using-the-gmail-smtp-server/

所有设置似乎都很好，测试电子邮件显示以下内容；

似乎连接和授权正常，但它导致没有发送/接收电子邮件。我试过 TSL (587) 和 SSL (465)

有人有解决办法吗？

谢谢

尝试将选项设置为不太安全http://www.google.com/settings/security/lesssecureapps

如果您也设置了 gsuit，请将两者都设置为不太安全。 http://admin.google.com/
