Specifying how Domino looks up the recipients of incoming SMTP messages
When Domino® receives a message over SMTP, the message recipient is identified by an Internet-style address, in the format Genevieve_Martin@renovations.com, rather than a Notes-style address, such as Genevieve Martin/Renovations. To determine the correct destination mail file, Domino must match the SMTP address to a Person document in the Domino Directory. To find a match, the Router checks the $Users view of the directory. This view displays all name entries in all Person documents in the directory, including Internet mail addresses, as well as all user name variations, first names, last names, common names (CN), distinguished names (DN), short names, and soundex names.
About this task
Inbound recipient lookups are controlled by the Address lookup setting on the tab of the Configuration Settings document. This setting determines the criteria that the Router uses when attempting to match the SMTP address on an incoming message to an entry in the $Users view.
The Router matches addresses based on:
- The full SMTP address only -- for example, Genevieve_Martin@renovations.com
- The local part of the SMTP address (that is, the part before the @ sign) only -- for example, Genevieve_Martin
- The full SMTP address, and then if no match is found, the local part address
When using full name matching, the Router searches the Domino Directory for an exact match of the entire SMTP address (for example, First_Last@Renovations.com). If an exact match is not found, the Router performs a secondary search if the domain suffix of the incoming address is listed in the Global domain document as an Internet domain alias. For this secondary search, the Router replaces the given domain suffix with the domain suffix designated in the Global domain document as the Primary domain name.
To prevent the Router from using domain aliases when looking up addresses, do not include alternate Internet domain aliases in a Global domain document. Instead, create multiple Global Domain documents, each specifying a different primary Internet domain.
Restricting the Router to matching addresses on the full Internet address only ensures that each user's Internet address complies with a standard format. Users cannot receive inbound mail addressed to their short names, soundex names, or other name variations that exist in the $Users view. When configuring the Router to look up users' full Internet addresses only, complete the Internet address field in all Person documents, and Mail-in database documents for mail-in databases that receive mail over SMTP.
