Restart the postfix daemon like this:
sudo /etc/init.d/postfix restart
Authentication
The next steps are to configure Postfix to use SASL for SMTP AUTH.
First you will need to install the libsasl2-2, sasl2-bin and libsasl2-modules from the Main repository [i.e. sudo apt-get install them all].
Note: if you are using Ubuntu 6.06 (Dapper Drake) the package name is libsasl2.
We have to change a few things to make it work properly. Because Postfix runs chrooted in /var/spool/postfix we have change a couple paths to live in the false root. (ie. /var/run/saslauthd becomes /var/spool/postfix/var/run/saslauthd):
IconsPage/warning.png Note: by changing the saslauthd path other applications that use saslauthd may be affected.
First we edit /etc/default/saslauthd in order to activate saslauthd. Remove # in front of START=yes, add the PWDIR, PARAMS, and PIDFILE lines and edit the OPTIONS line at the end:
# This needs to be uncommented before saslauthd will be run automatically
START=yes
PWDIR="/var/spool/postfix/var/run/saslauthd"
PARAMS="-m ${PWDIR}"
PIDFILE="${PWDIR}/saslauthd.pid"
# You must specify the authentication mechanisms you wish to use.
# This defaults to "pam" for PAM support, but may also include
# "shadow" or "sasldb", like this:
# MECHANISMS="pam shadow"
MECHANISMS="pam"
# Other options (default: -c)
# See the saslauthd man page for information about these options.
#
# Example for postfix users: "-c -m /var/spool/postfix/var/run/saslauthd"
# Note: See /usr/share/doc/sasl2-bin/README.Debian
#OPTIONS="-c"
#make sure you set the options here otherwise it ignores params above and will not work
OPTIONS="-c -m /var/spool/postfix/var/run/saslauthd"
