Free webmail risk
A caution signal when a business-looking request uses a free mailbox unexpectedly.
Why it matters
Free webmail is not automatically bad, but it can be suspicious in vendor, payroll, or invoice requests.
Example pattern
A vendor bank-detail change arrives from a free mailbox instead of the vendor domain.
