Yang ini mail dari sender yang sama, tetapi mail yang berbeda (isi, subject) nya.

http://mdaemon.dutaint.co.id/mdaemon/23.5/sp_outbreak_protection.html

Outbreak Protection is completely content agnostic, meaning that it doesn't rely on strict lexical analysis of message content. Thus, it doesn't require heuristic rules, content filtering, or signature updates. Further, that means it is not fooled by the addition of seed text, clever spelling changes, social engineering tactics, language barriers, or differences in encoding techniques. Instead, OP is based on Recurrent Pattern Detection and Zero-hour technologies. It relies on the mathematical analysis of message structure and message distribution characteristics over SMTP—it analyzes "patterns" associated with an email transmission and compares them to similar patterns collected from millions of email messages worldwide, which are sampled and compared in real time. Note: OP never transmits the actual content of messages, nor can message content be derived from the extracted patterns.

Oubreak Protection akurasinya sudah jauh lebih tinggi dibanding spamassassin, tetapi tidak bisa 100% akurat.
Dalam hal akurasi yang salah bisa dilaporkan ke altn.com.

https://knowledge.mdaemon.com/outbreak-protection-reporting

tetapi untuk pelaporan itu hanya bisa jika message sudah masuk ke queue, sehingga ada 2 pilihan bisa dilakukan:

1. Masukkan sender address kedalam antispam allow list no filtering

http://mdaemon.dutaint.co.id/mdaemon/23.5/sf_white_list.html

2, Outbreak Protection antispam accept message tetapi memberikan spam score positive.

Spam should be...

[x] accepted for filtering
