Confirming I have this problem too. My /etc/sshguard/sshguard.conf has
LOGREADER="LANG=C /bin/journalctl -afb -p info -n1 -o cat SYSLOG_FACILITY=4
SYSLOG_FACILITY=10"
The example provided by upstream has
LOGREADER="LANG=C journalctl -afb -p info -n1 -t sshd -t sendmail -o cat"
Changing it to this makes the problem go away. (Since I use postfix, I
used "-t postfix/smtpd" instead of sendmail.)
