Which of the following parameters are used by the Anti-Spam engine? (Choose three.)

Question

Options

• AThe number of recipients in the RCPTTO list.
• BThe characteristics of the message (random dots, multiple colors)
• CThe sending mail domains reputation
• DThe reputation of URLs in the message
• EAnalysis of image content using optical character recognition

• A
  9% (3)
• B
  88% (29)
• E
  3% (1)

Explanation

Anti-spam engines evaluate message characteristics (B) like random dots, multiple colors, and unusual formatting because spammers use these obfuscation tricks to fool basic filters. Sending domain reputation (C) is a core signal - known spam domains or newly registered domains with no history are flagged as high risk. URL reputation (D) catches phishing and malware links by checking embedded URLs against threat intelligence databases, since malicious links are a hallmark of spam and phishing campaigns.

A is wrong because RCPT TO recipient count alone is not a standard anti-spam parameter - it's more relevant to rate-limiting or anti-relay controls than content-based spam detection. E is wrong because OCR-based image analysis is a more advanced feature associated with Data Loss Prevention (DLP) engines, not the core anti-spam engine.

Memory tip: Think "BCD = Bad Content Detected" - the anti-spam engine looks at how the message looks (B), where it came from (C), and where it points (D).
