Poco Filter FAQ - Sample filters
Here are some sample filters that provide some examples of Poco's filtering capabilities.
Deleting Advertisements from the Server While Poco's junk mail filters provide excellent capabilities you can also code filters to handle known SPAM before it even reaches your computer. Some of the less intelligent spammers actually prefix the subject line of their messages with "ADV:". You can detect this and kill the messages before they even reach your computer.
Note the use of the "Case sensitive search" checkbox.
Resetting the Message Priority for Unknown Users This script demonstrates how you can override a person's designation of their notes as "High Priority". Normally Poco alerts you to high priority message by displaying the icon beside each message but people can abuse that feature. Here's a way that you can turn off this flag when reading messages. The technique below demonstrates how to do this for messages from people whose addresses are not in one of your address books.
Note the use of the "and" operator to join the two conditions and the use of the "match only if not found" to screen for email addresses not in one of your address books. (The %addressbooks% syntax is an undocumented feature that checks the indicated header against your address books to see if the address exists in it). You can also use this technique if someone you know is in the habit of crying wolf too often. :)
