DKIM keys
Selectors from your reports, the ones hosted here and common ones found in your DNS, looked up daily. Keys under 1024 bits are rejected by receivers; use 2048, and rotate a key after 365 days.
| Selector | Key | Age | Found | Notes |
|---|---|---|---|---|
| fm1 | Revoked | – | Found by lookup | – |
| fm2 | Revoked | – | Found by lookup | – |
| RSA 2048 | 0 d | Hosted here | – | |

| xero | RSA 1024 | 0 d | Seen in reports | A 1024-bit RSA key: use 2048 bits when you next rotate it. |

Failure reports
Individual messages that failed DMARC, as receivers reported them. They can hold personal data, so we keep only the sending details (no subjects, recipients or content), delete them after a short retention, and record every view in the audit log.
