Files Created/Modified

  • .env.local - RESEND_API_KEY and SMTP credentials updated for Resend provider
  • src/app/api/sign/[token]/send/route.ts - Sender domain updated to tcopelandhomes.com

Decisions Made

  • Resend chosen as the SMTP/email delivery provider — provides native DKIM signing support
  • Domain finalized as tcopelandhomes.com (not teressacopelandhomes.com) for sending address
  • DKIM selector is resend — TXT record at resend._domainkey.tcopelandhomes.com
  • DNS propagation confirmed complete via MXToolbox before resuming

Deviations from Plan

None - plan executed exactly as written. Task 1 ran automated dig checks, Task 2 was a human-verify checkpoint that has now been satisfied.

Issues Encountered

None. DNS propagation completed and all three records verified green. User confirmed with "dns verified".

User Setup Required

External services configured manually during this plan:

  • Resend account and API key created
  • DKIM TXT record added at DNS provider: resend._domainkey.tcopelandhomes.com
  • SPF and DMARC records configured for tcopelandhomes.com
  • RESEND_API_KEY added to .env.local

Next Phase Readiness

  • LEGAL-04 is fully satisfied — signing emails to real clients are authorized
  • All Phase 6 plans (01-06) are complete — the signing flow is production-ready
  • Phase 7 can begin; no DNS or email blockers remain
  • Signing links may now be sent to real clients with proper audit trail

Phase: 06-signing-flow Completed: 2026-03-21
