SpamSieve examines each incoming message and moves the spam messages into a separate spam mailbox. It leaves the good messages alone, so they will stay in the inbox or be processed by your other mail rules. In order to keep SpamSieve’s accuracy high, you’ll need to tell it about any mistakes that it makes:
You must correct all of SpamSieve’s mistakes or its accuracy will deteriorate over time. Also, the sooner you correct SpamSieve, the better. By promptly correcting SpamSieve, you ensure that it’s always acting based on accurate information.
If you make a mistake and tell SpamSieve that a message is spam when it is actually good (or vice-versa), simply correct yourself as you would correct SpamSieve. That is, if the message is good, train it as good; if it is spam, train it as spam. SpamSieve will “undo” the previous, incorrect, training.
Note: If you are accessing the same MobileMe/IMAP/Exchange account from multiple Macs running SpamSieve, it can be difficult to know which copy of SpamSieve needs to be trained to correct a mistake. It’s best to avoid this situation by using the drone setup or by only running one copy of SpamSieve at a time. Then you can just make sure to correct any mistakes before switching to another Mac. If you do need to run multiple copies of SpamSieve at once, filtering the same mail account, you should turn off auto-training.
Note: When using SpamSieve, turn off any other spam filters that you’ve installed. Disable any manual rules that you’ve created to catch spam messages, or transfer them to SpamSieve’s blocklist. This will make it clear which messages SpamSieve did and didn’t catch, which is necessary for you to be able to properly correct it.
