agent misclassified legitimate password-reset mail as credential phish after the template change and locked user...

  • Related public instructions; check applicability and missing conditions.

Fixes this failure: retune the classifier after the template change: add the new legitimate password-reset template's sending domain and header fingerprint to the allow training set. Use when the exact error or symptom in the title appears. Not for a different error, tool, or a manual process with no such failure.

When it applies

Not specified by the original author.

Instructions

TL;DR

Retune the classifier after the template change: add the new legitimate password-reset template's sending domain and header fingerprint to the allow training set, unlock the affected accounts, and require a second signal before the agent locks any account on a classification alone. Prove it on one message or campaign before rolling it to the rest of messages in the sweep or campaign, because this fault repeats identically wherever the same condition holds and a fleet-wide or batch-wide first attempt multiplies the damage when the diagnosis is wrong.

Use this when

  • You see this exact error or symptom: agent misclassified legitimate password-reset mail as credential phish after the template change and locked user accounts.
  • The failure is in the phishing triage agent and the mail or security APIs it calls, and it repeats on the same action rather than happening once and clearing.
  • Other items on the same path are working, so the path itself is up and this specific condition is the blocker.

Not for this skill when

  • A different error code, message, or tool is involved. Work that error's own skill, because the fix here targets this specific condition.
  • The whole service or platform is down. Restore the service first; this skill fixes the named condition, not an outage.
  • You cannot identify one affected item to test on. Find one first, because an untested fix rolled out broadly is how this fault gets worse.

Steps

  1. Confirm the fault on one message or campaign first and capture the evidence before changing anything: check the triage agent run log for the campaign, the gateway or Defender record for the same message, and the original message headers, and record the exact error text, the record or host involved, and the time it happened. Verify: you can point to the exact error and the exact item it belongs to, not just the symptom
  2. Retune the classifier after the template change: add the new legitimate password-reset template's sending domain and header fingerprint to the allow training set, unlock the affected accounts, and require a second signal before the agent locks any account on a classification alone. Verify: the specific fault named in the title no longer occurs on that item when you repeat the action that produced it
  3. Record the before and after state for this fix (the exact setting, record, or file changed) so the change can be reverted cleanly if the symptom returns in a different form. Verify: the guard or check is in place and is visible in the run, log, or configuration you changed
  4. Retest end to end: rerun the agent on the single campaign or message that failed and compare its verdict and actions against the gateway record. Verify: the retest completes without the original error and the resulting state matches what a manual check shows
  5. Roll the fix out to the rest of messages in the sweep or campaign in the same way, watching the first few for the same error, and note the root cause and the change in the run or incident record. Verify: the remaining items complete without the error recurring, or the ones that still fail are listed individually with their own evidence

The how-to phrasing for the same fault; start with the TL;DR fix, then work the steps in order.

Compatibility: Microsoft Graph and Defender, Proofpoint TAP, Mimecast, Google Workspace and sandbox services used by triage agents, as named in the title.

Why it happens

This fault happens because the fault sits at a boundary between two systems, each of which reports its own side as healthy, so the evidence has to be lined up on both sides to see it. In this case the condition is the one named in the title, in the phishing triage agent and the mail or security APIs it calls: the receiving or acting side reports the failure faithfully, but the underlying state (a record, a setting, a credential, a file, or a mapping) does not match what that action assumes. Fixing the state, as in step 2, clears it; retrying the action without changing the state returns the same error every time, which is why this failure looks stubborn until the state itself is corrected.

agent sent the password reset link to the wrong email address: template variable collision

  • Related public instructions; check applicability and missing conditions.

Prevents a helpdesk agent from sending a password reset link to the wrong email address: namespaced template variables and pre-send preview. Use when reset emails go to the wrong recipient. Not for email deliverability problems.

When it applies

Not specified by the original author.

Instructions

TL;DR

A template variable collision put the wrong address on the reset email. Namespace variables per recipient, preview the resolved message before sending, and require the address to match the ticket requester.

The query

agent sent the password reset link to the wrong email address: template variable collision

Use this when

  • a reset link went to the wrong address
  • the template has similarly named variables
  • the agent fills templates from multiple sources

Not for

  • reset emails landing in spam
  • SMTP or mail flow outages
  • link expiry problems

Steps

  1. Find the collision: two variables with the same name from different sources. Expected output: the conflicting sources are identified.
  2. Namespace template variables, such as requester email vs manager email, so they cannot collide. Expected output: each address has exactly one source.
  3. Add a pre-send preview that shows the resolved recipient to the agent. Expected output: the agent sees the real address before sending.
  4. Validate the recipient matches the ticket requester or an approved delegate. Expected output: mismatches block the send.
  5. Resend correctly and expire the misdirected link. Expected output: only the right person holds a valid link.

Applies to

Helpdesk email automation, password reset flows, any templated notification system.

Variant phrasings

Wrong address from stale ticket data

Refresh requester data at send time; tickets go stale.

Link sent to a shared mailbox by mistake

Shared addresses need explicit approval as reset recipients.

Why it happens

Reset links are your bearer credential A variable collision turns a convenience into a credential disclosure, so the send path needs the same care as the reset itself.

Edge cases

  • Log every reset-link recipient; the audit trail is the incident record.
  • Expire misdirected links immediately and notify the intended user.
  • Test templates with adversarial variable sets, not just the happy path.

password reset email goes to spam: how to fix

  • Related public instructions; check applicability and missing conditions.

How to fix password reset emails landing in spam: SPF, DKIM, and DMARC checks, plus what to tell users while you fix it. Use when users report reset emails in spam or missing entirely, when setting up transactional email, or during deliverability audits. Not for building auth systems, marketing email deliverability, or phishing investigations.

When it applies

Not specified by the original author.

Instructions

TL;DR

Reset emails land in spam for two reasons: your sending domain fails authentication (SPF, DKIM, DMARC), or the content looks spammy. Check authentication first with a deliverability test, fix the DNS records, then clean up the content: plain text-ish design, no URL shorteners, one clear link. While you fix it, tell users to check spam and add the sender to contacts.

The query

password reset email goes to spam: how to fix

Use this when

  • Users report reset emails in spam or missing
  • Setting up transactional email for the first time
  • Deliverability audits
  • "Never received the reset email" tickets spike

Not for

  • Building authentication systems
  • Marketing email deliverability
  • Phishing investigations
  • Email client bugs

Steps

1. Verify SPF, DKIM, and DMARC

Send a test to a deliverability checker and read the authentication results. Missing or misaligned SPF/DKIM is the top cause. Fix the DNS records: SPF authorizes your senders, DKIM signs the mail, DMARC ties them together.

Expected output: passing SPF, DKIM, and DMARC on test sends.

2. Check the sending reputation basics

New domains and new IPs start with no reputation. Warm them gradually. Check whether the sending IP or domain is on a blocklist. Shared IPs inherit other senders' sins; consider a dedicated IP for transactional mail.

Expected output: blocklist check clean, warmup plan if new.

3. Clean up the email content

No URL shorteners (they scream phishing), one clear reset link with your domain visible, minimal images, plain subject line like "Reset your [product] password." Spam filters score content too.

Expected output: a simplified, single-link template.

4. Give users the immediate workaround

While the fix propagates: check the spam folder, add the sender address to contacts, and search for the subject line. Put this in the reset-request confirmation page so users see it before they open a ticket.

Expected output: workaround text live on the reset page.

5. Monitor and confirm the fix

Watch reset-email ticket volume for two weeks after the change. Resend tests to the major providers. Deliverability is verified by customer behavior, not by one green checkmark.

Expected output: ticket volume back to baseline.

Template: the user-facing workaround

Did not get your reset email? Two quick things:

1. Check your spam or junk folder - it sometimes lands there.
2. Add [sender address] to your contacts, then request a new reset link.

The link expires in [time]. If it still does not arrive after that, reply here and we will sort it out another way.

Variant phrasings

reset email not received

Steps 1 and 4. Check auth, give the workaround now.

transactional email going to spam

Steps 1 through 3. Authentication, reputation, content.

SPF DKIM setup for reset emails

Step 1. The DNS records are the fix.

Why it works

Spam filters trust authenticated mail from reputable senders with clean content. Password resets fail the trust check most often on authentication, because they are frequently sent from a different system than the marketing mail that the domain was set up for. Fixing auth fixes the majority; content cleanup gets the rest.

Edge cases

  • Corporate filters stricter than Gmail: the user's IT may quarantine it. The workaround plus IT allowlisting covers this.
  • The user typed the wrong email: verify the address before debugging deliverability. Typos are common.
  • Apple relay addresses: sign-in-with-Apple users get mail at a relay address. Make sure your system sends there.
  • Link expired by the time they find it in spam: extend the expiry window or make re-request one tap.
