Continuing with security improvements all site and domain admins can apply: everybody that runs their own domain can and should implement SPF: Sender Policy Framework.
What it does, is explicitly tell the whole Internet which email servers are allowed to send email on behalf of your domain(s). Like many similar advertisements, this is achieved through DNS records.
