Features that might be of interest for Mailman: * There are more classes of users. On a moderated list, someusers can be set to have their posts automatically approved. There's also a list of banned users, who can follow the list but can't post.
You can do these things in Mailman, but it's more centralized. There is a listbox for each of these two things. Which do you think is more useful? Or both?
* Another list subscription policy: eSquire has open and closedlists as Mailman does, and adds a third level in-between, where any current subscriber can add new subscribers to the list.
Good idea.
* Unsubscribes can require approval (useful for work-relatedlists)
Good idea.
* You can create autoresponders. This is really orthogonal tomailing list handling, but you can create an autoresponder address which forwards any mail sent to it, and returns a response. For example, the author's e-mail is 'rrognlie', so he set up a forwarder for 'rognlie' to give people the correct address.
Is it as sophisticated as vacation? Ie, does it keep a database of who it's responded to recently to avoid mail loops, and the like?
So did you tell this guy about Mailman? What did he say?
