If you want to implement this yourself just realize that email is a text format. HTTP (2616) is actually based on RFC822 for format. That is important because receiving email requires a full understanding of the routing mechanisms defined in 821 and successive documents. Sending, though, just requires that you get 822 right because sending an email message only requires writing the contents correctly over a socket and DNS. Knowing that is how spammers can blast out millions of emails at almost no cost, because you don’t have to be an email server or client to send emails. |
