ezmlm is a mailing list manager written by Dan J. Bernstein. ezmlm-idx is an extension to ezmlm written by Frederik P. Lindberg and continued by Bruce Guenter. ezmlm has the essential features of a mailing list manager. ezmlm-idx adds useful, but non-essential features like digests, list moderation, etc. The list owner will have made the trade off of features vs. increased size and complexity. To test if your list has ezmlm-idx installed, send a message to ‘list-get@host’ where ‘list@host’ is the name of the list. A list with ezmlm alone will send you a help message saying that your message wasn't sent to one of its command addresses. A list with ezmlm-idx will return one or more messages from the archive, or a message telling you that the list is not archived. Throughout this manual, features available only with ezmlm-idx are marked with “(*)”.
