Mail SMTP Configuration

More Posted time:May 31, 2017 10:01 AM

I'm running an web application hosted on ECS (IIS v7) need to access mailserver to send out email. Any special configuration? Wondering if we have any documentation in english which will guide us thru the steps?

Thank you,

 Alibaba Cloud disabled port 25 for going out.

If you want to build mail server on ECS, we don't support using port 25, but suggest you using smtp, port 465, SSL to set up mail server.

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. If they can do that, then you can send request to their other port, and they redirect to port 25.
