Mailman as a bulk mailer – imported member managment tips

I have 20000 email subscribers for two email lists (cjobs and ucjobs). These were all imported into our new Mailman service.
I had a few settings I needed to change to accommodate using Mailman as a bulk mailer. And it’s going pretty well.
First there were normal things like pre-pending the default email subject, updating the list name and bounce protocols, making sure no-one can post to the list except the one authorized user (bulk moderate every user).
That was easy.

But then there’s a default setting where any list member can view all the other members of the list… not good.
First I updated the html docs, removing the relevant info.
Then I needed update all the users; but there’s no bulk operation for that.
Instead there’s a Member Mgmt screen with columns of check boxes. CheckBoxMate to the rescue…
Almost; Mailman displays a max of 30 members at a time… (20000 / 30 = ouch), that’s a lot of clicking and dragging. (more…)
