Can someone post a working example to send emails from ECS instances (preferably in python)?
The examples in this doc does not really work http://docs-aliyun.cn-hangzhou.oss.aliyun-inc.com/pdf/directmail-smtp-reference-cn-zh-2016-05-12.pdf since smtpdm.aliyun.com:25 can't connect Thanks! |

If you want to apply to open port 25, you can create a ticket. Support team will guide you. And then you can have a try again. Thanks

I really don't get it. Seriously your company needs to revise the security policy. Why on earth is the outgoing port 25 blocked by default? At least AWS, Linode and DO don't do that.

For ECS in VPC, you can apply to unlock in the console - risk control

Does anyone has the exact steps to unblock port 25 from the ECS console?
We just purchase an ECS to host our email server and now we are stuck due to this unexpected block for our email services. We really need help on this. |

Yes, port 22 is supported, normally used as SSH service.

Support engineer answered me that 25 port is blocked and suggested me to use any other port. This doesn't make any sense. It may have sense if he suggested to use external SMTP server, but to do that, I need to own an external SMPT server outside Aliyun, which I don't.
So there is no way to send email from Aliyun at all? Nobody uses email in China? Pls help |

We don't allow port 25 for setting up mail service, if you are not setting up mail server on the ECS, but calling 3rd party mail service provider, If you are using port 25 to connect to 3rd party mail service provider, please check with them if they can redirect the request from other port to port 25.
Sorry for the inconvenience. |

I would suggest to use third party email services, such as sendgrid, mailgun, mandrill, etc

You can use tcp protocol to send/receive email

Sad moment to discover such a totally unexpected stumbling block after having spent several weeks evaluating and to set up all the non-trivial features in our cloud server.
Reconfiguring to a third party email service on literally dozens of android-devices is a real PITA! Wish I knew beforehand...any chance of change in this seemingly meaningless policy anytime soon? |
