show license

License information
Who it was issued to and until when

Prints the license details: product and version, platform, the number of units and instances, licensee, serial number, issue date and expiry date.

There is no connection ceiling here: how many simultaneous connections are available given the license and the settings is shown by the “maximum” column in the show status output.

The main trap is looking only at the expiry date. A license can be valid and still cut the connection ceiling below what the node presets expect; that ceiling is visible in show status, not here.
What the Hub does. It does not call it. The Hub takes the license serial number from the /status response; it knows neither the expiry date nor the license tier (licensing).

When to call it:

Question This command or not
who the license was issued to and until when yes
how many connections it allows no — “maximum” in show status
The output layout comes from the manual (§ 6.3.30); the connection ceiling in the status output is § 5.3, § 6.2.1. The trap analysis is ours.
Example configuration
# license details and the connection ceiling
pmta show licensepmta show status
In the second output the ceiling is in the “Outbound” line, the “maximum” column.
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.
