Rewriting email and domain addresses

Administrator Help | Forcepoint Email Security | Version 8.4.x

An email envelope recipient address can be rewritten to redirect message delivery to a different address. Envelope sender and message header addresses can also be rewritten to mask address details from message recipients. You can configure address rewriting for inbound, outbound, and internal email on the Settings > Inbound/Outbound > Address Rewriting page.

You can export all the email or domain addresses in an address rewrite list to a text file by clicking Export when that list is displayed.

Remove an email or domain address from one of your address rewrite lists by selecting it and clicking Delete.

Use the Inbound Messages tab to specify recipient address rewrite entries for inbound messages and the Outbound and Internal Messages tab for outbound or internal message redirection.
