LuxSci has long supported SPF for inbound and outbound email. SPF is a mechanism by which you can specify what servers are permitted to send email for your domain … and identify email from other places that may be fraudulent. This helps stop inbound Spam and helps ensure that your own messages are distinguished from any fraudulently sent ones by your recipients.
DKIM (DomainKeys Identified Mail) is the other standard for preventing email forgery. DKIM works by cryptographically signing each email message sent. The recipients can use information published in your DNS settings to verify if the message was sent from an approved location (e.g. the signature is valid) and that it has not been modified in transit.
LuxSci now supports DKIM for both inbound and outbound email.
