Use Inbound Message Filters

Based on the inbound message filter criteria you set, incoming messages from customers or partners can be accepted or rejected.

Message filter patterns are specified using regular expressions. For example, to specify a filter pattern to accept all emails from Oracle employees, the regular expression is given as: ^[A-Za-z0-9._%+-]*@oracle\.com

You can set more than one filter. Filters are arranged in the descending order of priority on the Manage Email Filters page. The topmost filter has the highest priority. When a message comes in, the filter criteria are checked in the order of priority. If the first filter criterion doesn't apply to a message, the subsequent ones are checked. If any of the filter criteria match the incoming message, the message is accepted or rejected based on the filter specifications.

Note: It's important that you pay special attention while setting up email filters. If the User Messaging Service (UMS) setup rejects any email due to the filter setup, the rejected email can't be processed again by the application and it's lost.

To view the existing inbound message filters or to reorder their priorities:

1. In the Setup and Maintenance work area, go to the following:

   • Offering: Service

   • Functional Area: Communication Channels

   • Task: Manage Email Filters

   The Inbound Message Filters page displays a list of the existing inbound message filters.

2. If you want to change the priority of a filter:
   1. Select the filter whose priority you want to change.
   2. Click anywhere on the empty spaces in the selected row, and then drag the row to the required position.
