Configuring rejection behaviour

NOTE: Configuring the rejection behaviour is part of the configuration of rules. See Creating rules.

Here you configure how emails are treated that are rejected for reasons other than being suspected to be spam or malware.

The following basic options are available:

Reject and send a non-delivery report (NDR) for inbound emails. Discard and send NDR for outbound emails. The receiving server refuses acceptance (SMTP message 5xx). As a result, the delivering server must generate an non-delivery report (NDR).

Discard and send NDR for outbound emails. NoSpamProxy receives the email and sends a positive receipt to the sending server (SMTP message 200). The email is deleted immediately after acceptance; NoSpamProxy generates an non-delivery report and sends this to the delivering server.

Reject and send NDR for all emails. NoSpamProxy rejects the email, generates an non-delivery report and sends it to the delivering server.

Reject all emails without sending NDR. NoSpamProxy refuses to receive the email. The submitting server must generate an non-delivery report (NDR).
