As a result, only authorized providers (Orange, Free.fr, 9Tel, and other main foreign providers) can send more than the limit.
To avoid this limitation, use the mail server from your provider as a relay/smarthost for the domains:
- Navigate to Administration > IMSVA configuration > SMTP Routing > Domain-based Delivery.
- Add the following:
- Destination domain
- Mail server of your provider (FQDN or IP)
- Related port, which is normally port 25
