(IBM Lotus Domino 5.0 and higher)
Overview
To ensure the proper functioning of Sentinel Messaging’s Auto-Provisioning feature, it is crucial that your mail servers be configured to actively refuse
mail sent to undesired aliases during the SMTP transaction. We use the term undesired aliases to refer to e-mail aliases which have not been explicitly defined in
the “Internet address” or “User name” field of a Person document. For example, a user named “Joe Blow” with an “Internet address” of [email protected],
will by default receive mail for [email protected] and [email protected], even if you have not explicitly defined these e-mail aliases in the “User name” field.
Furthermore, this default behavior is conditional. If you have two users with a “First name” of Joe or a “Last name” of Blow, Domino will not enable this behavior.
As a result, it is highly desirable to disable this behavior in Domino, so that only explicitly defined e-mail addresses and aliases are accepted for SMTP
transactions, which we refer to as strict address lookup.
This tech note will help you enable strict address lookup within IBM Lotus Domino. If you have any questions about this or any other topic, please

Step 5
•
IMPORTANT: If you want each user to have a short address such as [email protected], be sure each user has an
“Internet address” set to the desired short address in their Person document:
•
IMPORTANT: E-mail aliases in the “User name” field must now be specified in Full name format
([email protected]) for the SMTP server to accept them.
IMPORTANT: The “Short name/UserID” field cannot be used to specify e-mail aliases when “Fullname only” address
lookup is enabled on the Domino server.
