Hi Stephen, I can't do that because may be the sender is on another MTA and mailman server can't force they do an authentication. Is this a weak point of Mailman ?
They still could connect and authenticate to the Mailman server's MTA for list posting purposes.
If for some reason they can't (e.g. their ISP redirects all port 25 connects to it's own MTA), you're back to Stephen's first remark - you can moderate everyone and post with an Approved: <password> header where <password> is the list admin or moderator password. Setting and using the moderator password is preferred to limit the damage in case it leaks.
