Managing custom filters

Initially, you will not have any custom filters. After you have created custom filters, they will be listed in the Filters list to the left.

  • To create a new filter, click [add] at the bottom of the Filters list.
  • To edit an existing filter, select it in the Filters list. Then in the summary area that appears, click [edit]
  • To enable or disable a custom filter, select it in the Filters list and click either [enable] or [disable]. Disabled filters will not be applied to incoming email, but they will stay present so that you can re-enable them later if you wish.
  • To permanently delete a custom filter, select it in the Filters list and click [delete]. You will be prompted for confirmation.

Adding and editing custom filters


Adding a custom filter (click for larger image in a new window)

While you are adding or editing a custom filter, other areas of the filter management tool will be disabled and greyed out. These will be re-activated when you Save or Cancel your edits.

The Save button only saves your changes to your browser. You will still need to click Apply to make the changes permanent and active on your account.

The configurable settings for custom filters are:

Filter name:

This is a descriptive name for your filter. It will appear in the Filters list to the left. Valid filter names contain alphanumeric characters and spaces.

When a message matches:

This controls how the conditions specified below should be grouped.

  • any of the following:  When this is selected, the filter's action will be taken if any of its conditions match
  • all of the following:  When this is selected, the filter's action will be taken only if ALL of its conditions match

Conditions:

These define the conditions under which a filter will match a message. A single filter must have at least one condition, and can have multiple conditions; multiple conditions will group together according to your setting for When a message matches, described above.

  • You can add and remove conditions by clicking [more] or [less]. Conditions added appear at the bottom of the list; removing a condition will always remove the last. The order of conditions is not significant.
  • A condition is made up of three parts. The three parts together create a simple sentence that describes when the filter should match.

A condition must have one of several match types. These are:

  • contains:   This will match an email if the specified text occurs somewhere within the selected field.
  • doesn't contain:   This will match an email if the specified text does not occur anywhere in the selected field.
  • is:   This will match an email only if the selected field contains exactly the specified text; no more, no less.
  • isn't:   This will match an email if the specified text is not an exact match for the selected field.
  • begins with:   This will match an email if the selected field begins with the specified text.
  • ends with:   This will match an email if the selected field ends with the specified text.

Note: When filtering based on email addresses, you generally want to use contains rather than is. This is because the From, To, CC, etc fields often contain additional information (eg full name), which can be arranged in a variety of ways. If a filter on one of these fields uses is, it will not match in many cases even though the actual address is the same.

Actions:

  • Leave the message in my inbox:   When this is selected, no action will be taken. Messages that match this filter will be left alone. This is useful for creating specific cases in which a later filter should not be applied.
  • Move the message to the folder:   When this is selected, the message will be placed in the folder you specify rather than in your Inbox. Your email client may or may not automatically see it in here - you may have to click the folder to make it notice there are new messages.
  • Forward a copy of the message to:   When this is selected, the message will be delivered to your Inbox. A copy of the message will also be forwarded to the address you nominate. When it arrives at this address, it will look as though the original sender had BCC'd the message to this address.
  • Delete the message permanently:   When this is selected, the message will be silently dropped. Since dropped messages are never stored on disk, it is impossible for these messages to be recovered from backup! Use with extreme caution, sparingly, and at your own risk. It is strongly suggested that if you wish to use this, first set up the filter to forward the messages to a special folder reserved only for this filter. Once you are sure that the filter is matching as expected, you might then change the action to delete.

Setting the order of custom filters

The order in which filters appear in the list is important. When an email arrives for your account, each filter in the list is checked in order. If a match is found, its action is taken and no more filters are checked.

This means that if you have a filter that needs to "override" the action of a second filter, it needs to be placed above the second filter in the list. If you have a filter that should be checked only if several other filters haven't already matched the message, it will need to be placed lower in the list. Generally, more specific rules should be placed towards the top, while more general rules should be placed towards the bottom.

  • To change the order your custom filters are checked in, select a filter and click either [move up] or [move down] at the bottom of the list. The selected filter will swap its position with the filter immediately above or below it.
  • The built-in spam and whitelists filter cannot be moved; spam and whitelist checking is always performed first, before any custom filters are checked.
  • New custom filters are automatically added to the end of the list.
