Looks like Mailman http://www.list.org/ http://www.list.org/ (except Mailman doesn't help with encryption, you have to figure it out yourself). FWIIW, my experience is that Microsoft Outlook and web-based email interfaces have trained users to use incredibly bad habits with email (crappy quoting, top posting (a subset of crappy quoting), 200K Word documents for a 5 line memo, megabyte .BMP screen shots, etc.). This really hurts email list usefulness until and unless the users improve their habits. Unfortunately... a) Outlook use is usually required by The Corporate Overlords. Even if it isn't required, users that don't know better insist on using it because it allows them to paste Mbyte .BMP screen shots into it. :-( b) While Outlook can be configured for usable quoting, nobody bothers to do so. c) Even if configured in the best way it supports, Outlook is still suboptimal. d) Web based email interfaces are generally even less configurable than Outlook and they all aspire to mimic Outlook, including promoting all of the crappy habits. --- The Hitchhiker's Guide to the Galaxy, in a moment of reasoned lucidity which is almost unique among its current tally of five million, nine hundred and seventy-three thousand, five hundred and nine pages, says of the Sirius Cybernetics Corporation products that "it is very easy to be blinded to the essential uselessness of them by the sense of achievement you get from getting them to work at all." In other words, - and this is the rock-solid principle on which the whole of the Corporation's Galaxywide success is founded - their fundamental design flaws are completely hidden by their superficial design flaws. -- The Hitchhiker's Guide to the Galaxy / Douglas Adams (1952 - 2001). 1st American ed.
