If you want to print a listing of your computer's mail queues, what command would you use?

`sendmail -l` is generally used for specific debugging or logging purposes with the Sendmail MTA, not for listing the mail queue.

`lpq` is a command used to inspect the print queue for printers, not the mail queue.

The `mailq` command is a standard utility on Unix-like systems, including Linux, that displays the contents of the mail queue managed by the Mail Transfer Agent (MTA), showing messages awaiting delivery or processing.

`mlq` is not a standard or recognized command for viewing the mail queue on Linux systems.
