What it means
Your mail signing key meets the bare minimum. Current guidance is double that. Worth rotating next time you're in your mail admin console.
The technical detail
1024-bit RSA is still acceptable per RFC 8301, but 2048 is the recommended floor.
How to fix it
- Rotate to a 2048-bit key under a new selector at your provider.
