Knowledge base
The same list, sorted
Prints queues by number of recipients in descending order. The manual calls it equivalent to show queues with –sort=rcpt; the options are the same.
Like show queues, by default it prints twenty queues and the latest recipient events.
The main trap is event noise. Along with the top, the command prints the latest recipient events; for an overview they are removed with –no-rcpt-events.
What the Hub does. It does not call it: it takes the top queues for the “PMTA monitoring” screen with the /queues request.
Recommended values
When to use it:
| Question | This command or not |
|---|---|
| the largest queues | yes |
| what the node held back | yes — –mode=backoff |
| all queues | no — show queues with –maxitems |
The equivalence with show queues –sort=rcpt and the set of options come from the manual (§ 6.3.19, § 6.3.14). The split of questions is ours.
Example configuration
# the largest queues without recipient events pmta show topqueues --no-rcpt-events
pmta show queues –sort=rcpt –no-rcpt-events gives the same.
yellow — — directive names, blue — blocks. They are highlighted the same way in the text of the card.
