Pipelining is a feature of the SMTP protocol that allows a client to send multiple commands at a time, and the server to send multiple responses at a time, instead of the client sending each command individually and waiting for the server to reply before sending the next command. The server still has to reply to each command in order, but the commands and responses can be grouped inside fewer TCP packets. You can simply opt to enable or disable this feature as you want.
