What this check tells you
Your test message doesn't just get inspected - it's run through the same policy engine JoltMx uses on real inbound mail. This check reports the decision that engine reached based on the message's authentication and reputation results:
- Accepted - the message passed and would be delivered.
- Quarantined - it would be routed to spam.
- Rejected - it would be bounced outright.
Think of it as a stand-in for a strict receiver enforcing DMARC and blocklists. The findings above explain why; this one tells you the bottom-line outcome.
Why it matters
It's easy to look at a wall of individual findings and not know how bad things really are. The disposition collapses them into a single answer: would this message get through to a tough provider, or not? If it says rejected or quarantined, fix the Critical and Warning findings above before sending anything that matters.
How the diagnostic grades it
| Result | Severity | What it means |
|---|---|---|
| Message accepted | Pass | The policy engine would deliver it. |
| Would have been quarantined | Warning | Receivers applying the same policy route it to spam. Address the warnings. |
| Would have been rejected | Critical | Strict receivers bounce it outright. Fix the failures first. |
An important caveat
This is a deliverability verdict, not a placement guarantee. "Accepted" means nothing mechanical is blocking the message - it doesn't promise the inbox over the spam folder, which depends on your reputation and engagement over time. See deliverability vs placement.
