The mailing list for listmasters using Sympa

["Roger B.A. Klorese" <address@concealed>]

Hello - some questions below, which will help me understand your 
assumptions and how to use or change it.

So your expectation here is that if $USE_SUBDOMAIN_SCHEME is set:
- you have a lists.DOMAIN subdomain
- you have control over both DOMAIN and lists.DOMAIN

And if it is not, whatever domain you're in, at whatever level, is also 
where the administrative addresses are.

...correct?

You describe an optional third argument, [extension] -- but never use it 
later, and if you get it here, die -- why?

Besides the misspelling of POSTMASTER, I am trying to figure out the 
logic here.

Are you saying that:
- the list owner is always set to either listmaster@DOMAIN or 
address@concealed -- no matter what the domain's config says is 
the address of the listmaster or what the list's config says is the 
address of the list-owner?

And mail to {root, etc.}@DOMAIN is treated as above, whether or not the 
administrators for the system are the same as the listmaster for the 
domain?  And what is this "listowner" alias?

So these will loop around through Sympa, and re-enter Postfix to be 
processed via the code above?

Other than the typo above ("unsubsCribe"), these are also queued or 
re-queued in the same way...

Wouldn't it make more sense for listmaster@ to be treated the same way 
as the "special" above, but without the listname, as in:

if($user eq 'listmaster') {
    exec('/usr/lib/sympa/lib/sympa/bouncequeue listmaster@'."$domain");
    exit(1);
}
