默认情况下，Elastic beantalk会阻止出站SMTP.故障排除指南中的步骤将向您显示(与服务器上的端口465的telnet或openssl连接将失败).真的没有更多了！亚马逊希望您使用SES接收电子邮件.这实际上是 AWS Elastic Beanstalk-MAIL(发送和接收电子邮件)的副本)

Elastic beanstalk blocks outbound SMTP by default. The steps in the troubleshooting guide will have shown you this (telnet or openssl connections to port 465 on your server would fail). There isn't really any more to it! Amazon wants you to use SES for email. This is really a duplicate of AWS Elastic Beanstalk - MAIL (Sending and receiving emails )
