edit /etc/spamassassin/local.cf for global rules.
Body checks:
body JUSTHEALTHY /www\.mb103\.com/
score JUSTHEALTHY 3.0
describe JUSTHEALTHY Spammer address detected in body
Header checks:
header MONEY_BAG Subject =~ /💰/
header BITCOIN_INVESTOR_LIST List-Unsubscribe =~ /bitcoin-investor\.ml/

Recommendation: add rules into ~/.spamassassin/user_prefs then test with a .eml file. They can then be moved into /etc/spamassassin/local.cf
Check your local.cf syntax by typing:
spamassassin --lint
To test an email (get the header report out):
spamassassin -t someemail.eml
Test an email with:
spamassassin < someemail.eml
From the command line, you can make sure spamassassin works by trying:
spamassassin -D
