How to setup and use the http/https/socks5 proxy to connect IMAP/POP3 server?

I checked the enough_mail document and no such content.

What's your use-case? If you have set up a proxy on your system, this should be transparent to any network app as far as I understand....

I'm chinese, my browser can open google.com when I use a proxy application

But I follow the example(High Level API) and try to connect google server(gmail account), the console show connect dns.google.com timeout.

I tried it on the flutter windows desktop mode.

BTW, I used the ThunderBird mail application, I can’t login to gmail when I use it by default, but it provided the network proxy settings, and I set the proxy to 127.0.0.1:7890, it can login gmail.

This seems to be an problem for Dart and Flutter, compare for example

• Network calls don't show in Charles Proxy Debugger flutter/flutter#20376
• Dart sockets don't respect iOS's VPN dart-lang/sdk#41376

I have found this GPL-licensed library that allows to connect via Socks5: https://github.com/v0l/socks5

One idea could be to abstract sockets in enough_mail and allow clients to specify a SocketFactory or similar.

Thoughts? Ideas? Suggestions?

It can be done like the dio package, allowing proxy settings https://pub.dev/packages/dio#using-proxy

import 'package:dio/dio.dart';
import 'package:dio/adapter.dart';
...
(dio.httpClientAdapter as DefaultHttpClientAdapter).onHttpClientCreate = (client) {
  // config the http client
  client.findProxy = (uri) {
    //proxy all request to localhost:8888
    return 'PROXY localhost:8888';
  };
  // you can also create a new HttpClient to dio
  // return HttpClient();
};

Dio just exposes the dart:io HttpClient's findProxy(Uri) callback. While I agree that this would be a nice API, I have no idea how to implement this. I cannot integrate with the above mentioned socks5 project, as that is licensed under the GPL-copy-left license and this does not mix with this project's MPL license.
So either this would need to be re-implemented or solved differently.

The underlying question is:

• how to connect with a Dart Socket through a socks5 proxy?
