[Mailman-Users] Sibling lists and list unsubscribe headers

[Tim]

Hi All,

I've set up a number of announce-lists and have nearly got things how I 
want them except for one issue.

Here is my setup:

3 lists - parentList, siblingList1, siblingList2

siblingList1 and siblingList2 are set in regular_include_lists for 
parentList.

user at domain.com is in lists siblingList1 and siblingList2

Everything is working perfectly as expected except for the list 
unsubscribe headers which refer to parentList.

Firstly, the unsubscribe will never work because user at domain.com is not 
subscribed to parentList, and secondly, unless messages are sent to 
siblingList1 and siblingList2 (which is infrequent), the user will never 
be given the opportunity to unsubscribe.

Is there anything I can do to make the headers etc match a list that 
user at domain.com is actually subscribed to?

I have searched high and low but can't find a solution to my problem so 
any help/pointers would be much appreciated.

Kind Regards,

Tim
