authorized senders

A dedicated RealSender smtp server is assigned to each customer.
This is the only way to keep control of the server’s reputation
and daily verify the senders’ domain reputation.

This approach requires that only the declared senders are given the green light to pass.
The system checks every message and accepts/rejects them based on the list of allowed senders.

The “authorized senders” for each RealSender account
must refer to one or more domain names registered by the same company.

RealSender partners and large organizations can independently update
the list of authorized senders.
