Emailing from the Command Line
Although email is an important service, only a few people know how it actu-
ally works behind the scenes. To send emails from an Arduino, we could
choose the easy path and use a PC as an email relay, as we did in Tweeting
Messages with Processing, on page 168, to Tweet messages. As real hackers,
we’ll follow a more sophisticated path and implement a subset of the Simple
Mail Transfer Protocol (SMTP).
