Question
- Should I set a higher or lower score in the Plesk Spam Filter?
Answer
The general rules for deciding which score to use state that you should start with the usage of Score 5 (Default) and proceed as follows:
- Lower the score if you find Spam emails are still making it through the filter
- Raise your score if you find that emails from legitimate sources are filtered by mistake
The table below outlines all of the available options:
| Score | Explanation |
| 1 | Aggressive - will mark many legitimate emails as spam (many false positives) |
| 2 | Mostly Aggressive - may mark a good portion of the legitimate emails as spam. (a medium amount of false positives) |
| 3 | A bit Aggressive - may mark a small amount of legitimate emails as spam. (a small amount of false positives) |
| 4 | More strict Middle ground - recommended for well-tested servers that still let some spam pass through after using score 5 |
| 5 | Middle ground (default setting, recommended as a starting point) |
| 6 | Less strict Middle ground - recommended for well-tested servers that still block some legitimate emails after using score 5 |
| 7 | A bit Passive - may let some spam emails through without marking them as spam (some false negatives) |
| 8 | Mostly Passive - may let more spam emails through without marking them as spam (a bigger amount of false negatives) |
| 9 | Almost entirely Passive - All legitimate emails will arrive, but so will many spam emails (lots of false negatives) |
| 10 | Severely Passive - All emails will arrive, but only the most obvious spam will be marked (the most false negatives) |
