Sending address summary
Who is busy with what right now

Prints the sending addresses in use: the number of domains, recipients, share, volume and connections. By default — all of them; –maxitems limits the list length, and the command has no other options.

A quick answer to whether an address is working. It does not show the effective limits — show vmta-settings is for those.

The main trap is looking here for all configured addresses. The command lists addresses in use: on a fresh node with no traffic yet, the Hub saw it empty with a full configuration.
What the Hub does. It calls it through POST /command with the node key — taking the names of addresses the engine actually knows, for operation targets in control. The “PMTA monitoring” screen takes the same data with the /vmtas request.
Recommended values

When to call it:

Question This command or not
which addresses are sending now yes
the limits and outbound addresses of one of them no — show vmta-settings
all configured addresses no — that is the configuration
The output columns and the “all” default come from the manual (§ 6.3.21). The observation about a fresh node is the Hub’s.
Example configuration
# addresses in use, no more than ten lines
pmta show vmtas --maxitems=10
The last output line says how many addresses are shown, for example “7 of 7 virtual MTAs.”.
yellow — — directive names, blue — blocks. They are highlighted the same way in the text of the card.
Compatibility
PowerMTA 6.0
described in the manual of this version · platform: any
The vendor does not state the first version for every directive — there is no note here. The name also appears in the 5.0 edition of the manual.

How to check on the node
Find out the number of addresses in use:
pmta show vmtas | tail -1
Zero on a node with configured addresses means there has been no traffic through them yet, not a configuration error.

◇Headers the sender uses to control deliverySix control headers let the submitting side choose a stream, tag a message with a job, set signing options and the key, the envelope identifier and the schedule; each is allowed separately and per source.◇Backoff mode — the queue's second personalityA queue that a receiver has started refusing switches to a parallel set of limits, retries and routes — ten directives that act only in this mode.◇Warm-up built into the engineA warmed-up address hands the first N messages of the day for each receiver to its cold partner; the partner sends them itself and builds history.
