If you look at the systemd unit for saslauthd, you can see this:

[Unit]
Description=SASL authentication daemon.
After=syslog.target 

[Service]
Type=forking
PIDFile=/run/saslauthd/saslauthd.pid
EnvironmentFile=/etc/sysconfig/saslauthd
ExecStart=/usr/sbin/saslauthd -m $SOCKETDIR -a $MECH $FLAGS
RuntimeDirectory=saslauthd

[Install]
WantedBy=multi-user.target



So all you have to do is edit /etc/sysconfig/saslauthd and put the
additional flags in the $FLAGS definition (which is empty by default).

Then the output of the saslauthd will be sent to stdout, which is
captured by the journal.  You can watch the journal for the saslauthd
service unit by running:

journalctl -xfl -u saslauthd.service
