Sender Policy Framework (SPF) - from their FAQ:

Sender Policy Framework (SPF) is an attempt to control forged e-mail. SPF is not directly about stopping spam – junk email. It is about giving domain owners a way to say which mail sources are legitimate for their domain and which ones aren't. While not all spam is forged, virtually all forgeries are spam. SPF is not anti-spam in the same way that flour is not food: it is part of the solution.

SenderId - a Microsoft technology which is very similar to SPF:

The Sender ID framework, developed jointly by Microsoft and industry partners, addresses a key part of the spam problem: the difficulty of verifying a sender's identity.

DomainKeys - from Wikipedia:

DomainKeys is an e-mail authentication system designed to verify the DNS domain of an e-mail sender and the message integrity.

DKIM - an evolved form of DomainKeys, from Wikipedia:

DKIM uses public-key cryptography to allow the sender to electronically sign legitimate emails in a way that can be verified by recipients. Prominent email service providers implementing DKIM (or its slightly different predecessor, DomainKeys) include Yahoo and Gmail. Any mail from these domains should carry a DKIM signature, and if the recipient knows this, they can discard mail that hasn't been signed, or that has an invalid signature.
