All the connection setup code was moved out of this library to avoid maintaining Socks5, OpenSSL TLS, Rustls and so on. Different users of the library have different needs for the type of streams they want to run SMTP on, maybe you want to run SMTP on top of your own tunnel or encryption layer or over QUIC or whatever. You probably also want to configure TCP timeouts on the socket before running Socks5 over it. If the connectivity code is part of async-smtp, you have to ask for each type of the stream and all kinds of TCP configurations to be added to the library and connection setup gets more and more complicated to support all the possible usecases.

This library is used by deltachat-core-rust and we have moved all the code related to connection setup including socks5 setup there, you can see how it works: https://github.com/deltachat/deltachat-core-rust/blob/20c88743dfd8e11c56a4c06e485b9618dc5cdf9d/src/smtp.rs

You can setup your own TCP socket, Socks5 and TLS, and then run this smtp-client on top of the connection.
