Mailing List Managers?
greyrax asks: "So I'm trying to convince someone to go open source for their list manager. They're about to upgrade to an expensive proprietary solution.
With about 400,000 subscribers to this newsletter, a database back-end would certainly be helpful. Bounced address management and easy unsubscribes is important (I've read Smartmail vs. MailMan comparison here). Virtual host support and a web interface are desirable. Any thoughts from the /.ers since this thread last year would be appreciated."
one thing i hate is having to "e-mail with subject \"help\" to receive a list of possible commands", each of which, I gather, includes sending an e-mail with a certain subject, then receiving an e-mail in confirmation of it. Blech!
Whatever you use, make sure it has a clean web interface, and configure it to include a link at the end of each e-mail sent to the group to the effect of "Click here to change or configure your mailing list membership."
