In Mailman 2.1, the cgi which gives the list of available mailing lists says something like this:
Below is a listing of all the public mailing lists on lists.samba.org. Click on a list name to get more information about the list, or to subscribe, unsubscribe, and change the preferences on your subscription. To visit the general information page for an unadvertised list, open a URL similar to this one, but with a '/' and the list name appended.
List administrators, you can visit the list admin overview page to find the management interface for your list.
Send questions or comments to mailman@lists.samba.org
A few people persistently interpret the "send questions or comments" as meaning "send samba user questions" rather than "send questions or comments about the mailing lists". This seems to happen a couple of times a week.
(Fairly reliably the people who make this mistake also send mail that is lacking in any useful detail and is therefore pretty pointless anyhow, but nevertheless they have to be forwarded or bounced.)
I think a better phrasing would be something like
"Please send problem reports about the mailing list to %s"
Ideally this text might be a per-site customization, rather than hardcoded in Mailman/Cgi/listinfo.py. I have fixed it there for the time being.
