Shows queues — “receiver and sending address” pairs. Without filtering this is “Top queues”: the ten pairs with the most recipients.
The “View Options” form sets filtering and list length: only queues with open connections, only without them or all; only in normal mode, only in backoff or in any; how many queues to show; order — by name, number of recipients or volume.
A queue paused by an operator and one held back by the node look alike but are treated differently: backoff mode shows with the mode filter, while the form cannot filter pauses — the show queues command with –paused=yes does that.
The same response as a structure — /queues?format=json.
Access is decided by http-access based on the address the browser is opened from — the monitor level is enough for viewing.
Which filter for which question:
| Question | Filter |
|---|---|
| which queues are stuck without connections | “without connections” |
| what the node held back | “backoff” mode |
| where small queues have errors | a longer list or order by name |
| what is paused | not on the page — show queues with –paused=yes |
# the form's filters in the console: all of backoff mode and pauses pmta show queues --mode=backoff --maxitems=1000 --no-rcpt-eventspmta show queues --paused=yes --no-rcpt-events

◇A queue is a receiving server together with a sending addressThe engine groups messages by the “recipient domain plus sending address” pair: one domain from two addresses is two independent queues with their own counters, connections and mode.◇Recipients deferred after a temporary refusalA recipient to whom the receiver responded with 4xx moves into a separate waiting area with a per-receiver interval; two commands can release it early.◇A retry ladder of your ownretry-after and backoff-retry-after accept a list of intervals — up to 30 steps, and the last one applies until the bounce.
