I have an Ubuntu 18.04 server running Postfix, Clamav, Spamassassin,
Dovecot with virtual hosts/emails.
I have spam sneaking in here and it is annoying. They all mostly come
from the same IP. When I ban the IP, after a few hours, it just comes
from another IP.
This garbage is obviously spam, no doubt. When I test any of the mails
via the command-line, it always scores high.
The last one I checked scored 23.8 as spam using either:
$ su spamassassin -c "spamassassin -D < testmail"
$ su amavis -c " spamassassin -D < testmail"
This one showed .6 in the X-Header as it came in as shown here:

X-Spam-Checker-Version: SpamAssassin 3.4.2 (2018-09-13) on
MyServer1-2.mydomain.com
X-Spam-Level:
X-Spam-Status: No, score=0.6 required=4.0
tests=BAYES_99,BAYES_999,DKIM_SIGNED,
DKIM_VALID,DKIM_VALID_AU,DKIM_VERIFIED,HTML_MESSAGE,
T_KAM_HTML_FONT_INVALID,T_REMOTE_IMAGE autolearn=no
autolearn_force=no
version=3.4.2
strange, BAYES_99+BAYES_999 scores 3.7
DKIM_VALID,DKIM_VALID_AU and DKIM_VERIFIED substract only 0.3 points
try setting sa_tag_level_deflt to 'undef' and you can see scores of those
rules...
