Where to look
- The Admin CP shows queued email, provider health, recent accepted submissions and failed attempts.
Why mail is waiting
- A provider limit was reached, so mail is deferred until capacity is free.
- Deferred mail is processed later through XenForo jobs.
- Queued mail survives interrupted workers.
Why mail failed or moved provider
- Temporary failures can move to a backup provider.
- Repeatedly failing providers get cooldowns.
- Expired security messages are not submitted after their deadline.
Check the route
- Use the route checker to confirm which rule and providers apply.
Check the provider
- Resend a test email, remembering it uses quota.
- Confirm the limits are not set too low.
