[Mailman-Users] accept_these_nonmembers @ notation

I have now upgraded to mailman 2.1.14 (to run on suse 11.3 with 
bundled python 2.6) and it runs nicely.

The help text for accept_these_nonmembers says

Add member addresses one per line; start the line with a ^ character to 
designate a regular expression match. A line consisting of the @ character 
followed by a list name specifies another Mailman list in this 
installation, all of whose member addresses will be accepted for this 

I succeed (not surprisingly, I tested this already on other installations) 
using regex. E.g. to allow posting to any list from root of any machine 
(which is exposed) this works

^root at .+\.lambrate\.inaf\.it

I cannot manage to have the @ notation working though.

I am testing this with two lists, pseudoastro of which I'm the only 
member, and pseudotecno (with a colleague as member, and me as non 
member). Ideally I'd want to set up a list as template and then work for 
all others (we will have some 6 DISJOINCT lists with categories of our 
staff, we want to be able that members of each can post to any other [and 
in addition to set up some umbrella lists])



fails at web level entry (Error: Invalid value for variable: 

Notation (with a blank between @ and list name)
@ pseudoastro
@ pseudotecno

gives an entry in the error log

  *_these_nonmembers in pseudotecno references non-existent list  pseudoastro
  *_these_nonmembers in pseudotecno references non-existent list  pseudotecno

I tried capitalizing the first letter, adding the host and domain, using
a notation list_host.domain (according to a posting found on the net), but 
in all cases I get the "non-existent list" error !!

What's the correct syntax ?

(and by the way ... are those checks to be considered effective as 
antispam measures ? do they just use the value of the header From field 
(which can be faked) or use info from the SMTP dialogue ?
