Enforced DKIM Filtering Eliminates Forged Email
Customers can add or upload lists of domains to be covered by DKIM checking (e.g. their own domains to start with) and can then say what should happen to messages when:
- a DKIM signature is present but is not valid
- no DKIM signature is present
- a valid DKIM signature is present
All LuxSci outbound email services support DKIM-signing messages; so enabling inbound filtering based on DKIM completes the loop of email authentication.
Premium Email Filtering also supports enforced use of SPF and TLS for inbound email from domains you choose. All of these things together serve to lock down your email flow and eliminate unwanted messages.
