What process handles the sending of the mail out to subscribers?

My new installation suddenly stopped sending. Apologies for so many newbie questions.

See <https://mailman.readthedocs.io/en/latest/src/mailman/docs/8-miles-high.html>

Incoming messages are received by Mailman's lmtp runner and queued in the in queue. They are picked up from there by the in runner and processed through a chain of rules and if accepted processed through a pipeline of handlers, one of which will queue the message in the out queue. Then the out runner will pick up and send the message.

Look at logs, particularly mailman.log, and queues and ensure Mailman and all the runners are running.
