SOCKS 5
Reply: success
address type: 1 (IPv4)
address: 10.212.1.1
port: 55243
The rest (starting at "42") is the IMAP handshake:
* OK .....
So we know that we connected just fine here.

As I said.

And here the engine is saying that it will tell QTcpSocket that it connected
fine, as expected.

We had 148 and the SOCKS5 reply was 10 bytes, so this is also correct.

Uh... that's the issue. The bytes here start with "* OK " and the length is
138, which is what was left from the previous parsing.
It's not that the SOCKS server sent two replies. This is a genuine bug in our
socket engine: the TCP packet contained the initial handshake from the server
and the socket engine got confused. It tried to parse the IMAP handshake as
another SOCKS5 reply.
