Using the Authentication Database

The Authentication Database (ADB) is a list of email addresses of which are either allowed or not allowed (blocked) to send you email messages.  Each address can have one of the following controls:


·        Allow Email From: If selected, messages from that sender address are always allowed.

·        Allow Everyone in Domain:  If selected, all messages from the given domain are allowed, except if other ADB address from the same domain have

Block Email From selected. In which case these individual addresses can be blocked, while allowing everyone else in the domain.  


Block Email From has precedence over Allow Everyone in Domain

·        Allow Distribution List:  If selected, that address is always allowed.


The messages  To and Cc addresses are authenticated for distribution lists, as subscribers are generally Blind Carbon Copied (Bcc).

·        Block Email From:  If selected, messages from that sender address are always blocked.  

·        Block Everyone in Domain: If selected, all messages from the given domain are blocked except if other ADB address from the same domain have   Allow Email From selected. In which case these individual addresses can be allowed, while blocking everyone else in the domain.


Allow Email From has precedence over Block Everyone in Domain

 Upon successful Passcode Authentication, a new address is added to the ADB with the  Allow Email From control.
