Outgoing Identity Setup
When configuring your servers to use Mail Assure outbound filtering, you need to choose the method by which the system should identify users sending mail.
There are three identification methods that can be used:
- Envelope sender - This uses the SMTP MAIL FROM address.
- Authentication User - This uses the same identity for all messages
- Identity Header - This uses a custom header, see Configure Identity Header Identification Method in Mail Assure and Your MTA
Unless you know that you specifically need to use the Authentication User or Identity Header method, we recommend using the Envelope Sender method since it requires no additional configuration.
In Mail Assure you set up the identification method in the Outgoing > Manage Users page, see Add an Outgoing User.
