You can choose the actions that are taken when email comes in that has a low, medium, or high probability of being spam. For each spam level, choose the action you wish to have taken. If you choose to add text to the subject line of messages, type the text in the box below the action drop down.
Content filtering is an advanced method of performing actions on emails that meet specific criteria. For example, you can use content filters to delete messages with certain attachments, forward messages from a specific email address to another account, or even alter the subject of specific types of email. Content filtering is very flexible in order to allow you to filter messages the way you want to.
To access your content filtering settings, click the settings icon. Then expand the My Settings and Filtering folders and click Content Filtering in the navigation pane.
To add a new filter, click New in the content pane toolbar. The content filter wizard will load in the content pane.
To edit an existing filter, select the desired filter and click Edit in the content pane toolbar.
Note: Content filters are executed in the order in which they show up in the list. When a content filter gets triggered and performs an action,no other content filtering is performed on that message. To change the order, click on the arrows next to a filter.
Content Filter Wizard
The New Content Filter wizard is three pages long, and it will walk you through each step necessary to create the filter.
Step 1 - Filter Criteria
In this step of the wizard, choose the type of things that the filter will look at. Possible filter criteria types are listed at the end of this help topic. Multiple criteria can be chosen, and you can choose in the next step whether all criteria must be met, or only one of the criteria for the filter to activate.
Step 2 - Filter Type and Criteria Details
Choose whether this filter requires one criterion to be met from each and every section, or just one of the criteria in any section to be met, before an action is performed. Then choose whether you will be using any wildcards in your search strings. Usually, wildcards will not be necessary, but there are times when some people may want them.
For each of the criteria you chose in step 1, you will be able to enter details. Many types of content filters allow lists of items to be entered in, and these will be indicated. For example, if you chose to filter on From Address, you can enter multiple email addresses in the box (one per line) and if a message is from any of them, that criteria will be met.
You also have the ability to reverse the logic of a specific criteria item by changing the "matches" box to "does not match."
Step 3 - Rule and Actions
A summary of your content filter rule will appear near the top of the page. Check that it is filtering the way you intend, and enter a name for the rule so that you can easily identify it later.
Choose one or more actions to take when a message matches this filter. The available actions are explained below:
- Delete message - Deletes the message so that it will never arrive at your Inbox. Messages deleted through content filtering are not recoverable.
- Bounce message - Sends a message back to the sender of the email saying that the message was bounced. Note that the message is still delivered to you unless you choose to delete it as well. Note: If the system administrator has disabled bouncing, this option will function the same as the delete action.
- Move message to folder - Delivers the incoming message to the folder you choose from the drop-down list. If you later delete that folder and leave the content filter active, the filter will automatically create the folder when the action is triggered.
- Prefix subject with comment - Useful for categorizing emails, the subject line will be altered to include the text you specify in the Comment box.
- Embed header line into message - Includes an email header into the message, which can be useful when performing additional filtering through Outlook or another email client. Headers should be formatted like "X-someheadername: value"
- Copy message - Forwards a copy of the message to another email address and leaves a copy of the message in your account as well.
- Reroute message to another email address - Forwards the message to another email address instead of this one. Will not store a copy of the email in your own account.
