[Techtalk] Routing mail

[Dan Richter]

Hi everyone.

As I understand it, a mail to me at foo.com may automatically be routed to 
mail.foo.com. But does anyone know how the SMTP server knows that mail to 
foo.com is actually supposed to go to mail.foo.com?

  Indeed, I've noticed a number of these [virus] emails today - I'd
  click on it, have a laugh and delete it. Of course, I run Linux so
  I am completely immune - Windoze users, do not try this.
