sendmail-beta - Mail transport agent. The most widely used, and the best IMHO. ChangeLog


# sendmail 8.12.11.Beta0
# ======================
# Slackware 9.0's 'sendmail' package includes version 8.12.8 and includes
# 8.12.10 in patches.  9.1 includes 8.12.10

# See the regular sendmail howto for the full 8.12.11 version

# Prerequisites:
# make
# gcc
# binutils
# fileutils
# m4
# OpenSSL (optional; for STARTTLS)
# Cyrus SASL (optional; for SMTP AUTH)
# OpenLDAP (optional; for LDAPMAP)
# Berkeley DB

# If you're replacing a Slackware installed sendmail, backup whatever
# files you need to, then run "removepkg sendmail sendmail-cf" to remove it.

# If you don't have user and group 'smmsp', add them:
getent group | grep "^smmsp:" > /dev/null || groupadd -g 25 smmsp
id smmsp > /dev/null 2>&1 || useradd -g 25 -u 25 smmsp

# Remove various patches and other files that we used to use/need for older
# versions, but don't need any more:

# Back-up your existing sendmail configuration files.  If your configuration
# files come from the sendmail-cf Slackware package, in Slackware 9.0
# they'll be in /usr/share/sendmail.
# If you have a source-installed sendmail in /usr/local/src (where this howto
# puts it) with your and files in cf/cf/, you can run
# this blurb below to back them up for you.  It assumes that you only have
# one version of sendmail's source in /usr/local/src.
# NOTE: be careful - if you keep your and in the
# last version's cf/cf/ dir and something goes wrong with this blurb,
# the next blurb will wipe them out along with the source tree.
# Make sure your old config files really do make it into
# ~/backup/sendmail/$OLDVER before you move past this part.

# MSP Usage
# =========
# Run this from cron every so often (every 15 minutes?) to flush
# the client queue.  Do this if you don't want/need to have a sendmail
# daemon running like the next example.
/usr/sbin/sendmail -Ac -q

# Run as an msp daemon with  The -L part will make it log
# 'sm-msp-queue' as the program name in syslog instead of 'sendmail'.
# -Ac means use instead of  The -q part tells it
# to flush the queue every 30 minutes.  This one will fork a process
# to run the queue.
/usr/sbin/sendmail -L sm-msp-queue -Ac -q30m

# Start a persistant queue runner (see -qp in the sendmail man page) using
#, 'sm-msp-queue' program name for syslog, sleep time of 1 minute.
# This one will have one persistant queue runner process that sleeps for
# a minute in between runs.
/usr/sbin/sendmail -L sm-msp-queue -Ac -qp1m

# View the msp mail queue:
/usr/sbin/sendmail -bp -Ac

# MTA Usage
# =========
# Run from cron to flush the mta queue:
/usr/sbin/sendmail -q

# Run as an mta daemon with  Use 'sm-mta' as the program
# name in syslog, flush the queue every 15 minutes.
/usr/sbin/sendmail -L sm-mta -bd -q15m

# View the mta mail queue(s):
# (they all do the same thing)
/usr/sbin/sendmail -bp -Am
/usr/sbin/sendmail -bp

# I have the /etc/rc.d/rc.sendmail script from Slackware 9.0 here:
# And if you want another one that'll handle starting/stopping/restarting
# sendmail, MIMEDefang, clamd, sophie, trophie, etc., grab this one:
cd /etc/rc.d
