Alternatives to Mailman?



I’ve been using Mailman for a couple of years (after using majordomo forever), but I’m growing impatient waiting for version 3. There are some simple things I’d like to do (allow users to get a list of names and e-mail addresses of other subscribers from the web interface) that just aren’t there and it’s not clear when they are coming.

Does anyone have any suggestions for other mailing list software that could be installed in the Dreamhost shared hosting environment? Or should I be looking at other solutions entirely?

[And I’d rather not get into a discussion of why mailing lists are last century’s solution. For some of the communities I support, they will be a key part of the solution for awhile longer – though RSS support in IE7 may start a change that will be faster than I expect.]
