Investigating New Sources
When new email sources appear, follow this process:
Step 1: Is It Expected?
Ask yourself:
- Did you add a new email service recently?
- Did you migrate to a new server?
- Is this a legitimate business tool?
Step 2: If Expected
- Find the source in SPF Management
- Verify the service name/IP matches what you expect
- Click Approve to add to SPF
Step 3: If NOT Expected
Security Alert
Unexpected sources may indicate unauthorized access. Check Risk Signals and reject sources with zero authentication immediately.
