You may want to investigate fudforum (PHP); http://fudforum.org/doc/d/html/features.mlist_nntp.html "FUDforum includes tools which will allow the forum to be used to archive newsgroups (NNTP) and mailing lists. In addition, FUDforum allows the administrator to permit forum members to post messages back to a mailing list or a newsgroup. This feature makes FUDforum an ideal access point to newsgroups and mailing lists for those who cannot access those resources directly." The documentation here may give you a better idea of what's on offer: http://fudforum.org/doc/d/html/admin.mailing_list.manager.html Fudforum would also make an good forum to "integrate" with Dokuwiki as it already has a clean API for embedding in other applications (you could display a discussion thread below a wiki page for ex.). Otherwise the lead developer recently authored a book on PHP security - http://ilia.ws/archives/2005/09/06.html (note remark he makes on phpBB)- he's someone who really knows what he's doing with PHP. -- DokuWiki mailing list - more info at http://wiki.splitbrain.org/wiki:mailinglist
