ezmlm fork with support for indimail-mta's multi-queue architecture.

This has been forked to adapt it to work with indimail-mta's multi-queue architecture. The three major changes that this version has made after the fork are

1. Ability to set environment variables in /etc/indimail/ezmlm/global_vars. You can create any file in this directory. The file name becomes the environment variable and the file content becomes the value of environment variable.
2. New queue program ezmlm-queue which can use qmail-qmqpc to use QMQP protocol, qmail-multi to queue mails to indimail's multi-queue instance or qmail-queue to queue mails to any qmta / qmail / netqmail / notqmail instance.
3. Use all common functions from libqmail library.

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, [email protected], with all relevant information stored in a new ~/SOS directory.

ezmlm sets up joe-sos-subscribe and joe-sos-unsubscribe for automatic processing of subscription and unsubscription requests. Any message to joe-sos-subscribe will work; Joe doesn't have to explain any tricky command formats. ezmlm will send back instructions if a subscriber sends a message to joe-sos-request or joe-sos-help.

ezmlm automatically archives new messages. Messages are labelled with sequence numbers; a subscriber can fetch message 123 by sending mail to joe-sos-get.123. The archive format supports fast message retrieval even when there are thousands of messages.

ezmlm takes advantage of qmail's VERPs to reliably determine the recipient address and message number for every incoming bounce message. It waits ten days and then sends the subscriber a list of message numbers that bounced. If that warning bounces, ezmlm sends a probe; if the probe bounces, ezmlm automatically removes the subscriber from the mailing list.

ezmlm is easy for users to control. Joe can edit ~/SOS/text/* to change any of the administrative messages sent to subscribers. He can remove ~/SOS/public and ~/SOS/archived to disable automatic subscription and archiving. He can put his own address into ~/SOS/editor to set up a moderated mailing list. He can edit ~/SOS/{headeradd,headerremove} to control outgoing headers. ezmlm has several utilities to manually inspect and manage mailing lists.

ezmlm uses Delivered-To header to stop forwarding loops, Mailing-List to protect other mailing lists against false subscription requests, and real cryptographic cookies to protect normal users against false subscription requests. ezmlm can also be used for a sublist, redistributing messages from another list.

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.

ezmlm uses functions from libqmail library. libqmail uses GNU autotools. You need to have autoconf, automake, libtool and pkg config package. Follow the instructions below to have them installed in case you don't have them.

$ cd /usr/local/src
$ git clone https://github.com/indimail/libqmail.git
$ cd /usr/local/src/libqmail
$ ./default.configure
$ make
$ sudo make install-strip

(check version in libqmail/conf-version)

NOTES

For Darwin (Mac OSX), install MacPorts or brew. You can look at this document for installing MacPorts.

FreeBSD
# pkg install automake autoconf libtool pkgconf

Darwin
# port install autoconf libtool automake pkgconfig openssl
# port update outdated

Arch Linux
# pacman -S --refresh --sysupgrade
# pacman -S --needed archlinux-keyring
# pacman -S base-devel diffutils coreutils openssl

Gentoo Linux

The build below depends on several Makefiles. For the build to operate without errors, you need to run default.configure the first time and everytime after you do a make distclean. If you don't run default.configure, you can replace make with ./qmake

$ cd /usr/local/src
$ git clone https://github.com/indimail/ezmlm.git
$ cd /usr/local/src/ezmlm/ezmlm-x
$ ./default.configure
$ make or ./qmake
$ sudo make install-strip

ezmlm is mailing list management software (MLM) by Daniel J. Bernstein. This version of ezmlm has been modified from the original to use re-usable functions from libqmail and work with indimail-mta.
