FTGate support both inbound DKIM checks and outbound DKIM signing.
Inbound DKIM checks
DKIM support is accessed though the Security policy SMTP tab.
The DKIM checking feature offers three options for handling DKIM validation failures:
- Ignore DKIM:
Do not process DKIM messages, allowing all emails to be delivered regardless of DKIM status. - Reject DKIM failures:
Process DKIM messages and reject any email that fails the DKIM check, preventing it from being delivered. - Reject DKIM failures but copy to Quarantine:
Process DKIM messages, reject failures, but also retain a copy of the rejected email in quarantine for further review.
