spamassassin.service: Failed with result 'start-limit-hit'

I am able to make this all work in one go in 3rd VPS

https://wiki.centos-webpanel.com/how-to-configure-spamassassin is what I followed with the following additional things

1. edit /etc/sysconfig/spamassassin had some code. Replaced that with

SAHOME="/var/lib/spamassassin/"
SPAMDOPTIONS="-c -m5 -u nobody -s ${SAHOME}spamd.log"

2. Used

systemctl daemon-reload

with

sa-update
systemctl restart postfix spamassassin

3.

nano /usr/lib/systemd/system/spamassassin.service

Added

StartLimitBurst=0

in last line of [Service] block as suggested here earlier

systemctl daemon-reload

The email with content

Thanks all for the support

systemctl daemon-reload
