Issue Spamassasin marking clean messages

[Jllynch]

I have some messages that are receiving a very clean score of -100! but getting marked as spam eg ****SPAM****. Note that the score is NEGATIVE, so clean. Can Spamassassin not work with 3 digits negative maybe? Any ideas?

Centos 7 - Plesk Obsidian Version 18.0.26,

From the email header:
X-Spam-Checker-Version: SpamAssassin 3.4.0
X-Spam-Level:
X-Spam-Status: No, score=-100.1 required=4.0 tests=BAYES_00,DKIM_SIGNED,
DKIM_VALID,HEADER_FROM_DIFFERENT_DOMAINS,HTML_IMAGE_RATIO_06,HTML_MESSAGE,
LOTS_OF_MONEY,PYZOR_CHECK,RCVD_IN_DNSWL_NONE,RCVD_IN_MSPIKE_H2,SPF_FAIL,
SPF_HELO_NONE,UNPARSEABLE_RELAY,URIBL_GREY,USER_IN_WHITELIST autolearn=no
autolearn_force=no version=3.4.0

There is no "X-Spam-Report:" on this email but there is on other messages that are real spam.

Thanks.

Any ideas?

Spam Protection

SpamAssassin is a rule-based mail filter that identifies spam. It uses a wide range of heuristic tests on mail header...

I'm learning too.

I would guess that the message gets marked as spam because the SPF failed. As noted in the X-Spam-Status header. Although I am not 100% sure about this.
