Mail Queue

Review messages waiting to be delivered and investigate why they are delayed.

Where to find it: Open the Server menu and choose Mail Queue.

Available to: Root only.

Before you start

Mail changes affect delivery and sometimes existing client connections. Confirm the exact address or domain, preserve credentials, and use delivery reports or the queue to verify the result.

Why use it — and when not to

Use Mail Queue for the selected account or server mail workflow. Use DNS Manager, Services, Mail Queue, or Delivery Reports instead when the problem belongs to delegation, service installation, queued transport, or delivery evidence.

How to use it

1. Find the delayed message using its sender, recipient or time.
2. Read its delivery details to identify the reason for the delay.
3. Retry delivery only after resolving the cause, or remove the message if that is intended.

Message inspection and delivery results

Inspect queued message content and delivery-attempt output before deciding whether a message should be retried or removed. A deferred message may be waiting on a temporary remote or DNS condition; the output identifies the reason.

Delete selected and Delete ALL have different scope. Confirm the exact queue IDs before deletion, and inspect a new delivery attempt after a repair rather than assuming that clearing the queue resolves the sending problem.
