Sure. From the web admin interface for your list, click on "Privacy
options...", and the first sub-page is "Subscription rules". Scroll
down to the "ban_list" field, which has the short description:
List of addresses which are banned from membership in this
Then you can either enter specific addresses which are banned, or you
can use Python regular expressions to ban an entire domain.
In the latter case, to take a couple of examples that were recently
banned on the mailman-users mailing list, we added:
This is because they had subscribed to the mailman-users list from
addresses that were themselves pointed at mis-configured mailing
lists, causing every single post to the list to result in a bounce.
When the people who administer these sites figure out that they've
been unsubscribed and their entire domain has been banned, they can
come back to us and ask why we took this action, and then we will
explain the severity of the situation to them. Once they can
convince us that this will never, ever happen again, we can re-enable
subscription access for their domain.
Note that there is no leading whitespace in these regular expressions
-- the caret ("^") symbol has to be the first character on the line.
