The workaround I finally used was to create a custom service file, separated from the original one shipped in the sasl2-bin package:
root:/etc/systemd/system# cat saslauthd-postfix.service [Unit] Description=SASL Authentication Daemon for postfix Documentation=man:saslauthd(8) [Service] Type=forking Group=sasl ExecStart=/usr/sbin/saslauthd -a pam -c -m /var/spool/postfix/var/run/saslauthd -n 5 [Install] WantedBy=postfix.service root:/etc/systemd/system# Note that I had to remove both the PIDFile entry and the RuntimeDirectory entry as they didn't play well with the chroot jail directory specified in the -m option. I also replaced the WantedBy=multi-user.target from the original file by WantedBy=postfix.service. best regards, Luc
