lists that are members of each other - bad idea?
I posted a question a couple of days ago about a particular Mailman set-up I wanted to achieve, but have since thought it would be better to ask a simpler and more specific question:
Does anyone know the consequences of setting up two lists which are members of each other?
I don't want to do something which will cause an endless loop and bring down the wrath of my hosting company upon myself!
Presumably the X-BeenThere header should come into play to avoid such an eventuality, but will it work in these circs? Or even if it does work, should one not do this sort of thing for other reasons?
Thanks

I believe that would be very bad news.Presumably the X-BeenThere header should come into play to avoid such an eventuality, but will it work in these circs? Or even if it does work, should one not do this sort of thing for other reasons?
The risk is that you will have set up a potentially serious loop, for which there is only one way to detect and stop it before there is a melt down. All it would take is a misconfigured client or MTA to remove certain headers before sending the message on, and you and everyone else would be toast.
Before you take a shotgun with a hair trigger and load it with thermonuclear shells, you might want to give some consideration to what it might do when you go away and leave it pointed in your direction -- especially when there are children and pets around, any one of which might accidentally set it off.

Kinda what I feared!
Does anyone have any suggestions about my original query then (about 'affilate' members a couple of threads back)?
Thanks

Not really. You could play around with the "topics" stuff, but I'm not sure that's going to do what you want.
I strongly suspect that you may have to hack some Python code to get Mailman to do what you want.

Was it that where you wanted to have some "not real members" be able to join in certain discussions they were allowed to? I think the best way to achieve your goal is to set up two lists.
