Anyone can forge an email header and send an email address as anybody else. It requires no hacking and all and the email spec does not contain any sender authentication. So for example, you could setup an email account in Outlook and use somebody else's email as the return address and it will work (want an email from the president?).

Spammers now often forge headers because it helps them get through spam filters and because the bounces go to someone else, which means another person got their spam.

@Robert Gentel,
Incidentally, while there's not much an individual user can do about it, the email providers can implement the Sender Policy Framework on their email domains to curb some of it. It would bounce the messages to some ISPs that look up the valid IPs for the email to originate from.
