Hi Phil,
******BULK MAIL****** Zope seems to be pretty robust in its mail tools (Zmail in, support for POP3 and IMAP, as well as the sendmail tag) but I could not find a product that provides listserv functionality. I also noticed that zope.org itself uses mailman (e.g., http://lists.zope.org/mailman/listinfo/zope-dev). Should I stick to mailman, or is there a product to do this?
Mailman is very mature and well-tested (read: scalable), and although it's not a Zope product and is not integrated with Zope, it is also written in Python. (It is actually maintained mostly by Barry Warsaw, a Zope/Pythonlabs employee). It's a good tool that has one (minor but sometimes annoying) limitation: subscriber logins cannot be shared between maillists. So if you have many Mailman-based maillists, people need to manage their logins and preferences for each separately. It also has a fairly weak archiver (Pipermail) that has no search capability. But it's an excellent tool. See this review: http://newsforge.com/newsforge/02/04/18/2327248.shtml?tid=51 Stephan Richter has written "ZMailman" which aims to integrate Mailman into Zope: http://www.zope.org/Members/srichter/Products/ZMailman . It doesn't look like its under active development, though. There is at least one other Zope-based maillist programs: MailBoxer at http://www.zope.org/Members/mjablonski/MailBoxer . HTH, - C
