Hello,
I would like to explain a sender what he can do to create an email

I cannot find the definitions on your old site
https://spamassassin.apache.org/old/tests_3_1_x.html.
FONT_INVIS_NORDNS, FONT_INVIS_MSGID, HTML_FONT_TINY_NORDNS, RDNS_NONE
Is there no current version of the test definition.
You can get the definitions directly from the rule files. On my system,
the updated rules are in
/var/lib/spamassassin/3.004006/updates_spamassassin_org.
describe RDNS_NONE Delivered to internal network by a host with no rDNS
describe FONT_INVIS_MSGID Invisible text + suspicious message ID
describe FONT_INVIS_NORDNS Invisible text + no rDNS
describe HTML_FONT_TINY_NORDNS Font too small to read, no rDNS
Since those make up the majority of the score, it looks like you should
explain to the sender that they should not be using tiny or invisible
fonts in their emails, and that they should fix the reverse DNS for
their mailserver.
