Fixed Sender Address Replacement (v2.50+)

Replaces the outgoing sender address with a fixed address. Useful when a relay provider requires a specific sender address (e.g. the authenticated account address).

Private email override: Users can mark a message as “Private” (via the Sensitivity field in Outlook) to bypass sender replacement for that message.
