No confirmation e-mails even “Receive acknowledgement mail when you send mail to the list?” has been set to “Yes”

A list administrator asked me whether it is possible for the sender to receive an email confirmation when he’s mail has been approved by the list administrator or moderator.
I found some documentation on how to achieve this<http://www.list.org/mailman-member/node24.html>*) and I tried it on my test list, which have two members: My corporate mail and my private Gmail account. My corporate e-mail is owner if the list, both are subscribed to the list as moderated member, and both members have set “Receive acknowledgement mail when you send mail to the list?” to “Yes” at http://mailman.foo/roster/mylist.
But I do not seem to receive any confirmation e-mails to any of the e-mail addresses, once I have approved the mails and they have been sent to the members, neither last Friday nor today.
I am using Mailman 2.1.12
This is logs from today:

The user option “Receive acknowledgement mail when you send mail to the list?” does not work with anonymous lists because at the time we decide to send the acknowledgement, all trace of who sent the mail has been removed. That is why the second of the pair of entries in the post log has the list address rather than your address.
If you set your list's General Options -> anonymous_list to No, the poster should receive requested acknowledgements.
This could be considered a bug. If you report it at <https://bugs.launchpad.net/mailman/+filebug>, I'll fix it.
