Official domains and email policies
Domains reviewed as belonging to TSMC. DMARC helps receivers check the From domain; lookalike domains remain possible. Published policies cannot confirm actual mail configuration or receiver behavior.
| Domain | Relationship | Evidence | DMARC policy | Policy source | SPF | Reporting | DKIM | MTA-STS | Last check | |
|---|---|---|---|---|---|---|---|---|---|---|
| tsmc.com | primaryReviewed — | Portfolio directory (wikidata_cik+financedb_ticker) | Not checked | Not checked | Not checked | Not checked | Not checked | Not checked | Not checked | Not checked |
“Not checked”: no check yet (mail, DKIM and MTA-STS facts were added later, so older checks show “Not checked” for them). “Lookup failed”: DNS result unknown. DKIM is probed at a fixed list of common selectors only. Report mailbox names are redacted.
Reports on official domains appear under “Official assets with reports” on the Reported matches tab.
