I am using a Sophos UTM 9 SG210 firewall and noticed in the SMTP log that a formerly trusted sender has had 50 legitimate emails rejected. I've since added them to an exemption list, but was wondering if there is any way to retrieve those rejected emails? The reason for rejection was SPF check failed.

SPF checks occur early on in the conversation so the sender (probably) doesn't get a chance to send the email before the attempt is rejected. So no, they're not recoverable.
