"I sent a quote this morning and the customer says nothing arrived." That is the question this screen exists for. It shows, per message, what the mail server did with it: accepted, deferred, bounced or refused — and when it went wrong, what the receiving server said about it, in its own words.
You find it on the account under Email → Delivery log, or directly at /accounts/<account>/mail/tracker.
What you do and do not see
You see the envelope only: who wrote to whom, when, how big, and what the other end answered.
You never see the subject and never the content. That is not an oversight but the rule the whole feature rests on: a log with subjects in it would be a searchable archive of everything ever mailed through the server. So none of the content is stored — not even "briefly".
The four states
| State | What it means | What to do |
|---|---|---|
| Accepted | the receiving server took the message | nothing — it was delivered |
| Deferred | the other end did not want it right now; the server keeps trying | wait; usually greylisting or a full mailbox |
| Bounced | it was accepted and then permanently failed | read the reason; usually an address that does not exist |
| Refused | the server turned it away at the door | incoming mail; usually spam, or an address that does not exist here |
Accepted means the next server took it over. What that server does with it afterwards — inbox or spam folder — nobody outside can see, including your hosting provider.
Searching
Four tiles at the top show the counts. Press a tile to show only that state; press it again to drop the filter.
Beside them you search by address. Part of one is enough: @customer.com shows everything from and to that domain. Searching for quote finds nothing — the content is not searched, because it is not there.
One message in detail
Click a row and a panel slides open with everything known about that message: each recipient separately, with the code, the server that answered, how long it took and the sentence the other end sent back. For example:
nobody@example.com bounced 5.1.1 host mx.example.com said:
550 5.1.1 User unknownThat is usually the answer straight away: User unknown is an address that does not exist (a typo, or somebody left the company), Greylisted is a delay that resolves itself, over quota is a full mailbox at the other end.
If one message went to three people and one failed, the message is listed as bounced and the panel shows which of the three it was.
How far back
The server keeps 30 days. There is nothing older in this screen — the charts under Statistics go back further, but they only count and name no addresses.
From the command line

You see the mail of your own domains and nobody else's. An administrator can open the same screen for a whole server (Servers → a server → This server's mail delivery) or for the whole platform (Statistics → Mail delivery).
