Here is the lifetime of a typical email message before the rise of anti-spam solutions, and how the designers of SMTP envisioned it:

Using a mail client such as Mozilla Thunderbird, Kristy writes me a message and clicks 'Send'.

Her mail client connects to her ISP's (say, Comcast's) mail server, tells it from whom the message is and where it's going, and gives it the message itself.

Comcast's server accepts the message and leaves a mark on it, stating that this message was received from Kristy's computer by Comcast's systems at X o'clock.

Comcast's server looks at where this message needs to go, and makes a connection to that host. For example, if the destination is someuser@qnan.org, it connects to mail.qnan.org because that's where I configured mail destined for qnan.org to go.

My server accepts the message from Comcast and leaves another mark on it, stating that this message was received from Comcast by qnan.org at Y o'clock. My server then delivers the message to my mailbox.

I use a mail client to access my mailbox and read the message. I can also see the complete path of this message, from Kristy all the way to me, which theoretically allows me to complain to Comcast if Kristy is spamming me.
