Using TLS authentication (Transport Layer Security)
If a message is sent via TLS then RiskFilter will be able to receive it, if STARTTLS Advertisement is
enabled. However, if your mail server will only accept messages that are sent using TLS, then TLS must
be enabled in RiskFilter in order for mail to be delivered to this server. See Certificate on page 25 for more
information.
To set up domain-based delivery:
1Select Send Settings > Domain-Based Delivery from the System Settings tab.

messages sent by TLS transfer regardless of it’s settings. However, if your mail server requires TLS
authentication to DELIVER mail, then you must enable TLS mail delivery.
To enable TLS delivery, select My server(s) require communication over transport layer security.
12 For more information on TLS see Certificate on page 25.
13 Select My server(s) require authentication if you want users to supply a username and password
before they can access the server.

15 Click Submit to put the new settings into effect or Reset if you want to cancel the modifications made
to the current settings.
Note: if your server does not require TLS for mail delivery, do NOT select this feature as this
will stop settings from being submitted.
