Server port 25 is blocked, and no other protocol ports are configured, how to JS send mail?

Aliyun"s server port 25 is blocked, and the application cannot be unblocked for many times, and the customer"s mail server is only configured with port 25 protocol. Now you want to use js to send mail directly on the browser, and the environment is in the official account of Wechat. Is there any js that can be implemented like this?

it is not a good design for the browser to send mail directly. Your server port 25 is blocked, just that it can't be a mail server, but it should be able to send mail. Your server can send mail even if it connects to a SMTP server.
