## Session Summary

Winter reported that emails from `lindsay@agencyzoomify.com` were again going to trash when sent to `y226@tedards.net` (Yvonne Tedards), referencing Syncro ticket #32228 opened 2026-04-30. Context was pulled from the 2026-05-01 session log, which showed the prior investigation diagnosed the root cause but applied no remediation — a comment was posted to the ticket explaining the issue to the customer, but the ticket was left at New status and no allow rule was created. Winter confirmed this and asked for a fix to be applied.

The root cause, confirmed via DNS investigation: Lindsay sends emails from the Wirechunk CRM platform (an insurance-agency website/CRM tool). Wirechunk routes outbound mail through WPCloud servers (IPs 103.115.9.0/29 and 103.115.10.0/29), which are authorized in `agencyzoomify.com`'s SPF record but do not sign outbound mail with DKIM for the `agencyzoomify.com` domain. Because `agencyzoomify.com` carries `DMARC p=quarantine` and Wirechunk provides no DKIM alignment, Microsoft EOP applies the quarantine action and routes the messages to Yvonne's trash. By contrast, emails from Lindsay's husband arrive normally because he sends directly from Outlook via the `theboltonagency` Microsoft 365 tenant, which has both `selector1` and `selector2` DKIM keys properly published for `agencyzoomify.com`.

A permanent Tenant Allow/Block List (TABL) sender allow entry was added for `agencyzoomify.com` on the Tedards M365 tenant using the Exchange Operator MSP app (cert auth). The entry carries no expiration date. Syncro ticket #32228 was resolved with a public customer-facing comment explaining the fix. Mike then directed a deeper investigation to identify the specific CRM involved (Wirechunk), confirm why the husband's emails worked differently, and draft an outreach email to Lindsay explaining the issue and asking her IT/Wirechunk to enable DKIM signing. The email was sent from `mike@azcomputerguru.com` to `lindsay@agencyzoomify.com` with `y226@tedards.net` CC'd. A second public comment summarizing the full findings and fix was posted to the Syncro ticket, and 30 minutes of remote labor was billed and invoiced ($75.00).

---

## Key Decisions

- **Permanent TABL allow (no expiration):** This is an ongoing business relationship between Yvonne and Lindsay. A 90-day expiry (used for the Dataforth/Joel Lohr case in the same 5/1 session) would just cause the issue to recur. Permanent allow is appropriate here since the underlying DMARC problem is on Lindsay's end and may take time to resolve.
- **TABL at tenant level, not per-mailbox safe sender:** Tenant-level allow overrides DMARC quarantine action for all mailboxes in the tenant. Per-mailbox `TrustedSendersAndDomains` also works but is mailbox-scoped; since the fix is domain-level and the issue is authentication-based, TABL is the correct tool.
- **Identified Wirechunk as the CRM, not just "a CRM":** The `agencyzoomify.com` SPF record includes `_spf.wpcloud.com`, which resolves to two specific Australian IP blocks. The agencyzoomify.com website embeds Wirechunk platform identifiers (`siteId`, `platformId: gz3p2m`) in its page source. This allowed the outreach email to name the specific platform rather than speaking vaguely about "a third-party mail service."
- **Email sent from mike@ not admin@:** `admin@azcomputerguru.com` is not a licensed user or shared mailbox in the ACG M365 tenant — it returned 404 from Graph. The ComputerGuru Mailbox app (`1873b1b0`) can only send as real mailboxes; `mike@azcomputerguru.com` was used. The signature block still references `admin@azcomputerguru.com` as the reply-to contact.
- **Phone number corrected to 520-304-8300:** Draft initially included 480-388-0700 (wrong); Mike corrected it before send.

---

## Problems Encountered

- **`admin@azcomputerguru.com` not a valid mailbox:** Three attempts to use it as the Graph `sendMail` user resulted in 404 `ErrorInvalidUser`. Resolved by sending via `mike@azcomputerguru.com` with `admin@` referenced only in the body signature.
- **Shell variable expansion mangling vault fields:** Early attempts to pass `cert_thumbprint_b64url` and `cert_private_key_pem_b64` via bash variables failed silently — the shell was mangling the values, causing 401 `AADSTS700027` (wrong certificate thumbprint). Resolved by hardcoding the values directly in the Python script for the mailbox token acquisition, and by using `bash .claude/skills/remediation-tool/scripts/get-token.sh azcomputerguru.com mailbox` (the correct suite tool) for subsequent calls.
- **TABL `Notes` field length limit:** First TABL POST failed with a 400 error asking to remove 59 characters from the Notes field. Resolved by shortening the notes string to 81 characters.
- **`New-TenantAllowBlockListItems` `PageSize` parameter rejected:** Initial message trace attempt included `PageSize` which triggered `AmbiguousParameterSetException`. Removed the parameter; the cmdlet accepted the remaining parameters without it.
- **Message trace returned no agencyzoomify.com messages:** No messages from that domain appeared in the 9-day trace window for y226@tedards.net, and the junk/deleted folders were also empty. Lindsay had not emailed Yvonne recently enough to appear. Root cause was confirmed via DNS analysis instead.
- **Syncro ticket ID mismatch:** The display ticket number (#32228) does not match the internal Syncro API ID (109697650). The `/api/v1/tickets/32228` endpoint returned `{}`. Located the correct ticket via subject search (`query=agencyzoomify`).

## Pending / Incomplete Tasks

- **Lindsay's IT / Wirechunk:** Needs to enable DKIM signing for `agencyzoomify.com` on the Wirechunk platform. Outreach sent 2026-06-25. No response yet. If they respond needing technical guidance, the fix is: in Wirechunk's admin/domain settings, generate a DKIM key pair for `agencyzoomify.com`, then publish the provided CNAME or TXT record in agencyzoomify.com's DNS.
- **TABL entry is a workaround:** If Wirechunk fixes their DKIM, the TABL entry becomes unnecessary but harmless. No action needed unless there's a reason to remove it.
- **bt@tedards.net DELETE folder:** Unexplained by server-side config. EOP delivers all Lindsay messages cleanly. Client-side Outlook behavior suspected. Bill or Yvonne need to check Outlook junk email settings on Bill's machine. Could also add safe sender for agencyzoomify.com on bt@tedards.net mailbox (TABL and transport rule already cover it tenant-wide).
- **Wirechunk test to Tedards pending:** No Wirechunk-origin messages have been traced to bt@tedards.net or y226@tedards.net in 10 days. To confirm the DMARC fix is working for Wirechunk → Tedards path, Lindsay needs to send a test from Wirechunk specifically to a tedards.net address.
- **GuruProtect (ACG inbound) breaking DMARC for agencyzoomify.com:** When Inky adds a warning banner to agencyzoomify.com emails arriving at ACG, it breaks DKIM body hash, causing DMARC to fail at final ACG delivery. One "Testing" message from Lindsay went to ACG junk because of this. An ACG-side TABL for agencyzoomify.com would fix this, or GuruProtect could be configured to suppress banner for that domain.
- **Mike will resume this investigation on ticket #5070.**

## Update: 19:11 PT — bt@tedards.net trace, Lindsay replies, GuruProtect analysis

### Summary

After context compaction, Mike continued the investigation with a focus on new information: Yvonne Tedards reported emails from the Lindsay/Bill conversation were ending up in Bill's DELETE folder and disappearing in real-time (count dropping 5 → 4 → 3 while she watched). Mike also received a response from Dmitriy (Lindsay's IT/Wirechunk) who clarified that Wirechunk sends from the `platform.agencyzoomify@wirechunk.site` envelope sender, not `agencyzoomify.com` — and that DKIM for agencyzoomify.com is not the right fix, that adding agencyzoomify.com as a custom sending domain in Wirechunk is the correct approach.

Mike asked several clarifying questions: which emails were being allowed before (the husband's direct Outlook emails), whether the original analysis was correct (mechanism correct, specific envelope sender domain was wrong — said boltonselect.com, correct is wirechunk.site), and what his name/email was (not captured in prior investigation; confirmed he's Brandon Bolton at brandon@agentive-one.com, sending from agentive-one.com domain in the theboltonagency M365 tenant).

Investigation extended to bt@tedards.net. ACG mailbox trace found Bill (not Yvonne) had forwarded three messages to mike@ labeled "BOLTON #1/2/3 in DELETE FOLDER." Message trace for bt@tedards.net (10-day window) showed all Lindsay messages as Delivered with clean 2-event traces ("Message received" → "successfully delivered"). Zero Wirechunk messages delivered to bt@tedards.net in 10 days. No server-side inbox rules (18 rules, none matching agencyzoomify.com), zero sweep rules, no blocked sender entries for agencyzoomify.com. Message trace detail (Get-MessageTraceDetailV2) on all five Lindsay → bt messages confirmed clean delivery with no rule-fire events.

GuruProtect/Inky analysis: ACG uses GuruProtect for inbound email. Tedards does NOT use Inky. When Bill's BOLTON forwards arrived at ACG, GuruProtect added its warning banner (External / First-Time Sender). The "Testing" email from Lindsay that went to junk at ACG failed because GuruProtect modified the HTML body (banner insertion) which broke DKIM body hash, and Inky's outbound IP (34.210.15.192) is not in agencyzoomify.com's SPF → DMARC fails at final ACG delivery. Mike corrected an erroneous assumption that Tedards also used Inky.

Lindsay replied three times to the outreach email: confirmed she added Dmitriy to resolve the Wirechunk issue, asked if she should start a new email chain, and sent a Wirechunk test ("Sent. Refer an Agency to AgencyZoomify") which GuruProtect tagged as Graymail and delivered to ACG inbox. Session ended with Mike requesting a save; will resume on ticket #5070.

### Additional Key Decisions

- **DELETE folder at bt@tedards.net is client-side:** All server-side investigation was exhausted (message trace, inbox rules, sweep rules, junk config). EOP delivers cleanly. No server-side explanation found. Conclusion: Outlook client junk filter or manual user deletion. Did not attempt to fix without clearer evidence of cause.
- **Correction logged:** Initial session incorrectly identified boltonselect.com as the envelope sender domain for Wirechunk. Correct envelope sender is platform.agencyzoomify@wirechunk.site (per Dmitriy). Our applied fixes remain valid regardless.
- **GuruProtect assumption corrected:** Briefly implied Tedards may also use Inky based on routing headers. Mike corrected: only ACG uses Inky. Correction logged to errorlog.md.

### Additional Problems Encountered

- **Get-MessageTraceDetail deprecated:** Returned 400 with deprecation notice pointing to Get-MessageTraceDetailV2. Switched cmdlet, no further issues.
- **ACG mailbox Graph search for "Testing" returned unrelated results:** $search="Testing" matched too broadly. Found the relevant message by searching junk folder directly with from: filter.
- **Inky IP breaking DMARC at ACG:** Lindsay's direct Outlook "Testing" email went to ACG junk because GuruProtect modified body → broke DKIM → DMARC failed at final hop. Not a Tedards issue; ACG-side problem. Unresolved; potential fix is ACG-side TABL for agencyzoomify.com or GuruProtect domain allowlist.
