Arduino send email error in documentation

hello,

there error in code snippet 1 @ https://playground.arduino.cc/code/email

the code send "auth login" command missing in code snippet 1 @ above link. while executing code, got " 500 - unrecognized command" smtp server.

the correct working code below:

/*

please correct above page in documentation.

thanks!

i don't know talking about. code in playground (for smtp2go section):

code: [select]

  serial.println(f("sending auth login"));
  client.println("auth login");
  if(!ercv()) return 0;

  serial.println(f("sending user"));
// change base64 encoded user
  client.println("xxxx");

  if(!ercv()) return 0;

  serial.println(f("sending password"));
// change base64 encoded password
  client.println("yyyy");

  if(!ercv()) return 0;

the first example not need auth login.
