Filters automatically sort your incoming messages into folders that you create using the Yahoo! interface. (To learn how to create filters using your POP mail client, please refer to your client's help files.) They work according to rules that you set up — for example, you could create a filter that automatically delivers messages from your family members to a personal folder called "Family". Filters can save you time, since you don't need to read through each message to decide where it goes.
Business Email owners may create up to 200 filters.
Create a Filter
Mail Options Menu: Filters
Filters: Add Button
Set up criteria for the filter:
Choose the field you want to match in the incoming message: sender:, recipient:, subject:, or body.
Choose the criterion by which you want a match to be made, such as contains, does not contain, begins with or ends with.
Now enter the text that you want to compare in at least one of the fields above, such as @rocketmail.com, love, recipes. When a new email message arrives, the filter will check to see if this text appears in the field you specify; if it does, the filter will transfer the message to the destination folder you select.
Choose the destination folder to which you would like the message delivered if there is a match. For example: Personal or News.
Filters: New Folder Name
When you're done, click the Save button.
Filters: Save Button
Note: If you have more than one filter, you'll see "up" and "down" arrows above the list of filters on the Filters page; you can use these buttons to reorder your filters whenever you'd like. Filter order is important: Filter 1 will be the first filter applied to an incoming message, Filter 2 will be the next, and so on, until a match is made or all filters have been applied. If no filters match an incoming message, it will be delivered to your inbox.
Editing or Deleting a Filter
On the Filters page, click on the name of the filter you would like to edit or delete. The filter rules will appear to the right and can be edited. If you edit your filter, be sure to save the changes.
To delete a filter, select the filter by clicking on the filter name in the Filters list and then click the garbage can icon above the list.
