Axigen Mail Server - Request authentication for local deliveries as an anti-spam measure

This article describes how to configure Axigen Mail Server to request authentication for local delivery email messages, sent by a local domain to another local account, as an anti-spam measure.

Solution

NOTE that the following SMTP Acceptance rule is able to test only the envelope headers, leaving the examination of the From and To message headers up to the anti-spam application you use with Axigen Mail Server.

From the Webadmin interface, go to Security & Filtering menu, Acceptance & Routing context, Advanced Settings tab and click Add Acceptance / Routing Rule. In the New Acceptance / Routing Rule wizard proceed with the following:

Write a suggestive Rule name for this rule
Leave Enable this acceptance/routing rule ticked
From the Conditions list, select Sender Domain and click Add Condition
Write your local domain name in the Sender domain field
From the Actions list, select Delivery Local and click Add Action
Set Local delivery to Allow delivery for authenticated users
Click Save Configuration to save and apply the rule

Example:

For multiple domains, proceed with the following:

Write a suggestive Rule name for this rule
Leave Enable this acceptance/routing rule ticked
From the Conditions list, select Sender Domain and click Add Condition
Write your first local domain name in the Sender domain field
From the Conditions list, select again Sender Domain and click Add Condition
Write your second local domain name in the Sender domain field
Leave actions to apply for incoming messages that match ANY of the conditions below
From the Actions list, select Delivery Local and click Add Action
Set Local delivery to Allow delivery for authenticated users
Click Save Configuration to save and apply the rule
