and you couldn't make the spam disappear with a simple magic trick?
If the solutions work or not depends on the rest of the internet, but in my book it never hurts to set everything up.
With SPF you add records to the DNS of your domain listing the server ips which are allowed to send emails for this domain. If the receiver has SPF setup his mail server will check the envelope-from domain and retrieves the list of authorized server ips from the DNS. If they match the email goes through, if not it depends on their config on what happens with the email (usually rejected)
An addition to SPF is Sender ID
The concept with DomainKeys is that the sender signs the message with a key, the receiving mail server fetches the public key from the DNS of that domain and verifies the message.
SPF is widely used, DKIM not so much
