Hi,
I was just discussing Mailman features with our user-support person. One idea we had (not directly related to the web interface) is a test address for every list.
The purpose is to test a list setup without spamming everyone. So, if we had a list foo@example.com, it would be nice to be able to send an email to foo-test@example.com and get back an email saying what would have happened if I'd emailed the list.
The result might be a standard bounce, but alternatively, it might say "your email was accepted, and would have been delivered to 16 addresses, including 4 other Mailman lists on this server. 3 other recipients have no-mail set". Where a list member is another Mailman list on the same server, that list should be sent an email to its test address, and so on, recursively.
Of course, if the new interface manages to be sufficiently simple and robust, the need for test addresses might be reduced.
