5.3.6   Show Blocklist

The Show Blocklist command in the Filter menu opens the Blocklist window. The blocklist consists of a list of rules. If a message matches one or more enabled rules on the blocklist (and Use SpamSieve blocklist is checked), SpamSieve will predict that it is spam. As always, SpamSieve does not prevent you from receiving the spam messages; rather, the blocklist ensures that they will go to the spam mailbox rather than the inbox. You can also configure Apple Mail so that the blocklisted messages go directly to the trash.

Creating Rules

There is normally no need for you to manually create or delete blocklist rules because SpamSieve learns to recognize your spam automatically. If a lot of spam is in your inbox, your first step should be to follow the instructions in Why is SpamSieve not catching my spam? rather than to create blocklist rules that may not be needed or even used (e.g. if the real problem is that your mail program isn’t set up properly).

Rules and Training

By default, the Train SpamSieve blocklist preference is enabled. This means that SpamSieve will automatically create blocklist rules when you train a message as spam. You won’t get spam from the same address or sender name twice.

SpamSieve will also disable matching blocklist rules when you train a message as good. This prevents a bad blocklist rule from blocking similar good messages.

Editing Rules

You can edit a rule’s Header or Match Style by clicking in the corresponding column and selecting from the pop-up menu. To edit a rule’s Text to Match, double-click the text. For more information about the available options see the Rule Columns, Headers, and Match Styles section.

Deleting and Disabling Rules

You can delete a rule from the blocklist by selecting it and pressing Delete. Generally, there is little reason to delete rules. SpamSieve is optimized such that having lots of rules does not reduce performance.

If you don’t like what a rule is doing, you should uncheck the rule rather than deleting it. This will prevent SpamSieve from re-learning the rule automatically (see “Rules and Training” above). For example, say that you get forged spam messages from your own address. When you receive such a message, and tell SpamSieve that it’s spam, any rule on the whitelist with your address would be disabled. This will enable future such spam messages to be caught. If you later get a legitimate message from your own address and tell SpamSieve that it’s good, the whitelist rule will remain disabled, so SpamSieve will still be able to catch that spam. If you had previously deleted the rule instead of disabling it, telling SpamSieve that the message was good would create a new, enabled whitelist rule, which would prevent those spam messages from being caught.

Finding Rules

You can type the first few letters of a rule’s Text to Match to quickly locate that rule, or use the search field in the toolbar to focus on a group of related rules.

Troubleshooting Rules

Blocklist rules will not match a message if:
