This may seem a little bit strange a question. How do you know if your mail sent through Mailman is getting to all members of your particular list.

If you check your logs, that will tell you what has made it off your machine and has been accepted by the remote systems. Beyond that, you can't be sure that any of those recipients have actually seen the message in question. The only way you can be sure is if they respond to the message.

suspect the problem might lay with the anti-spamming rules of the server on which I operate - they only allow so many messages to be sent through a mail box each hour. What I don't know is how Mailman reacts to this, does it process according to the server's anti spam rules or does it just roll over and die, not completing the task?

It depends on how they implement their restrictions. If they issue 5xx permanent errors, then Mailman will consider those recipients to have bounced. If they issue 4xx temporary errors, then Mailman will retry those messages at a later time.

But if you're already running into limits being placed on you by your service provider, you're already in a pretty bad place. I would encourage you to find another provider who does not place such limits on you, or who works with you to ensure that everything works the way it should.
