Plus addressing is a feature that allows you to automatically filter your incoming email without creating content filtering rules first. To demonstrate this ability, consider the example of plus addressing below.
Assume your email address is firstname.lastname@example.org, and you want to sign up for a newsletter called ACME News. Furthermore, you want that newsletter to go to a folder in your email called "ACME". Assuming you have plus addressing enabled, as described in the next section, all you have to do is sign up for the newsletter with the email address below:
Note that the folder name is AFTER the username but before the @example.com.
When the newsletter gets delivered to your email, it will automatically be placed in an ACME folder, which will be created automatically if it does not already exist. No additional steps are required. The whole process is automatic once you enable the feature.
In addition, if you include the '/' character in your plus address, you can automatically create sub-folders, as in the following example:
This email address will create a folder called Newsletters, then create an ACME folder under it, and drop the newsletter into the ACME folder.
As an added bonus, you can connect to folders in your email using POP3 by using plus addressed emails. The example above, when input into your POP email client as your login name, will return the contents of that folder.
Enabling Plus Addressing
In order for plus addressing to work, it must first be enabled for your user. Follow the steps below to turn the feature on:
- Log into webmail.
- Go to the Settings menu and choose My Settings.
- Click on the Plus Addressing tab.
- Check the Enabled checkbox.
- Choose an Action to perform when a plus addressed email comes in:
- Move to folder - If the target folder exists, the incoming message will be placed into it. If the folder does not exist, it will be created. No more than 10 folders can be auto-created in this method during a six hour period to prevent abuse.
- Move to folder (if it exists) - If the target folder exists, the incoming message will be placed into it. Otherwise, the email will get placed in the Inbox.
- Leave in Inbox - Drops the message into your Inbox.
