But does the haproxy negotiate a handshake with the client? Isn't it just proxy passing through to the submission server? I thought the client is doing the handshake with submission server but is connected with haproxy server. Or did i miss understand how that works? Does haproxy have to do another handshake to the submission server for postfix to talk to the client?
