![]() ![]() If you flunk one of those tests, notify your HTML designer or email service provider (ESP), pronto. The scores vary according to how SpamAssassin is configured, and users can boost or reduce them if they want.Īlso, SpamAssassin penalizes messages more heavily for factors you might not control, such as using open relays or blacklisted IP addresses, or using malformed HTML or MIME ( define) coding. They can also decide which tests to apply. Habeas accreditation can take 4.3 (for single opt-in) to 8 (for confirmed/double opt-in) points off your score, for example.Ī couple negatives, besides the rejection potential: End users, whether individuals or corporations, can set the maximum score as high or low as they want, although a score of 5 or so is most common.

If your email is rejected, the ISP or receiving business may provide this detail in a bounce message not inform you (the sender) at all or simply insert the word “SPAM” at the beginning of the subject line when the message is delivered to the recipient.Using a word such as “free” too often in copy might cost half a point, but the filter won’t reject your message outright as some others do. Though it can reject permission-based messages, SpamAssassin has many positives: Check out the list of tests to get a basic understanding of what SpamAssassin checks for. But the message can also receive negative points (a good thing) that help offset the unwanted positive points. If a message scores too many points, SpamAssassin rejects it. When a message flunks a test, it scores anywhere from a fraction of a point to multiple points. In a corporate setting, usually small to midsized businesses and ISP mail servers, it runs each email message through hundreds of tests that analyze headers, text, and HTML coding and checks domains and IP addresses against DNS ( define) blocklists and filtering databases.
