# apt-get install sasl2-bin libsasl2 libsasl2-modules
Now edit /etc/default/saslauthd:
START=yes
Now we should create /etc/postfix/sasl/smtpd.conf :
pwcheck_method: saslauthd
mech_list: PLAIN LOGIN
Ok, let’s add some lines in /etc/postfix/main.cf to enable SASL:
smtpd_sasl_auth_enable = yes
smtpd_sasl_security_options = noanonymous
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination
postfix does a chroot so it can’t communicate with saslauthd. This is the tricky part:
# rm -r /var/run/saslauthd/ # mkdir -p /var/spool/postfix/var/run/saslauthd # ln -s /var/spool/postfix/var/run/saslauthd /var/run # chgrp sasl /var/spool/postfix/var/run/saslauthd # adduser postfix sasl
Now restart postfix and start saslauthd
# invoke-rc.d postfix restart # invoke-rc.d saslauthd start
