Why didn’t my email get through?
You have been directed to this page because you tried to send email to someone whose mail is handled by the Tartarus mail system, which decided that your email was probably spam.
Tartarus uses a spam detection system called SpamAssassin. This works by comparing each email with a series of rules, each of which is assigned a score. The total score for the email (the total of the scores of each rule that is satisfied for the email) is then compared against a system value; if the total is higher, then the email is rejected. Copies of rejected email only are kept locally so we can investigate problems with this process.
What should I do?
If you sent an email that was incorrectly identified as spam, then the best thing to do is to edit the email so it doesn’t trigger so many SpamAssassin rules. These rules should be listed by name in the error message you will have received when your email was rejected (the same message that pointed you to this page). These are terse, but you should be able to identify enough to rewrite your email successfully.
SpamAssassin is a very common filtering tool, and in cases of incorrect blocking, we consider it the responsibility of the source site to generate emails that do not look like spam; we can provide some advice here if asked politely. We will not alter the rules at our end, since that will impair our ability to reject real spam. Remember that email should not be considered a reliable mechanism for communication.
