Set up Sender Policy Framework (SPF) records in DNS.
SPF is an e-mail validation system designed to prevent e-mail spam by tackling source address spoofing, a common vulnerability. SPF allows administrators to specify which hosts are allowed to send e-mail from a given domain by creating a specific SPF record in the public Domain Name System (DNS). Mail exchangers then use the DNS to check that mail from a given domain is being sent by a host sanctioned by that domain's administrators.
