We use a Barracuda Spam Filter at work, and we also provide a mass emailing program to some of clients that send out newsletters. Lately one of them's been composing his latest company newsletter and has been trying to send preview messages to himself, but they've actually been quarantined by Barracuda as potential spam, even though they aren't. I can see the breakdown of the spam scoring headers in Barracuda, but I'm not sure what certain rules mean. Here's the breakdown:
pts rule name
description
---- ---------------------- --------------------------------------------------
0.00 FUZZY_CPILL BODY: Attempt to obfuscate words in spam
2.21 HTML_IMAGE_ONLY_24 BODY: HTML: images with 2000-2400 bytes of words
0.00 HTML_MESSAGE BODY: HTML included in message
0.50 BSF_SC0_SA_TO_FROM_ADDR_MATCH Sender Address Matches Recipient Address
1.00 BSF_SC0_SA392f Custom Rule SA392f
What is "Custom Rule SA392f"? Where do I find descriptions of these custom rules? And what does "images with 2000-2400 bytes of words" mean? Is that referring to the file size of the image, or something about the attributes on the <img> tag?
