Yes, certainly, though a check of the sending IP DNS and a complete list
of valid recipients stop a lot more spam than my blacklists do. Even
requiring a thirty-second timeout stops a lot, no legitimate mail
server minds waiting that long.

The social problem of the existence of thieves and idiot marketing

come in my lifetime.

Indeed, which is why I pretty well gave up on content analysis. My
usual email client dumps a few really egregious subjects, but otherwise
I rely on a well-trained mail server. The email address above is
genuine, and has been used on Usenet and various web-published forums
for more than eighteen years, and still only about half a dozen spams a
day make it to my mailbox. But things are improving, I only reject
about a hundred a day, and ten years ago it averaged more than a
thousand a day. My record was more than twelve thousand...
