Easy-to-use, high-speed mailing list manager for qmail
ezmlm is an easy-to-use, high-speed mailing list manager for qmail.
ezmlm lets users set up their own mailing lists within qmail’s address hierarchy. A user, Joe, types
ezmlm-make ~/SOS ~/.qmail-sos joe-sos isp.net
and instantly has a functioning mailing list, firstname.lastname@example.org, with all relevant information stored in a new ~/SOS directory.
ezmlm takes advantage of qmail’s VERPs to reliably determine the recipient address and message number for every incoming bounce message.
ezmlm is reliable, even in the face of system crashes. It writes each new subscription and each new message safely to disk before it reports success to qmail.
ezmlm doesn’t mind huge mailing lists. Lists don’t even have to fit into memory. ezmlm hashes the subscription list into a set of independent files so that it can handle subscription requests quickly. ezmlm uses qmail for blazingly fast parallel SMTP deliveries.
