It's easy to make a mess of things, overloading recipient mail systems, etc. Within an organization there are some different considerations than a mailing to the same number of people on the Internet, as the recipients are likely to be concentrated on a lot fewer systems. We do mass mailings to about 28,000 people in our organization with LISTSERV. We've put considerable effort into trying to do it with minimal impact, while still making things as easy as possible for the users and the moderators. I'd be glad to discuss the particulars by voice with anyone interested. It's too much to type in.
