MAIL

Setting up a server to receive mail for multiple Internet domains
Every organization has a primary Internet domain name -- for example, acme.com -- by which it is known to the rest of the world. By default, IBM® Lotus® Domino® considers the local, primary Internet domain to be the domain specified in the server's host name. For example, for a server with the host name Server1.acme.com, both Server1.acme.com and acme.com are considered local Internet domains. The server does not accept messages addressed to recipients in any other Internet domain.

In addition to having a primary Internet domain, some organizations use alternate Internet domain names. If your organization uses more than one Internet domain name, you'll want Domino to consider other domain suffixes as local. Using multiple Internet domain names typically results when:

If for any of the preceding reasons people in your organization have addresses in an Internet domain other than the primary domain, create a Global Domain document. A Global Domain document identifies the Internet domains that are considered to be internal to a Domino domain and for which the local domain can accept mail. By default, the Domino Directory does not contain a Global domain document. Within the Global Domain document, you specify one primary Internet domain name and multiple secondary domains. Secondary domains are listed as alternate Internet domain aliases.

You must ensure that the DNS is set up to include all the Internet domain names that your company uses.

To create a Global Domain document

1. Make sure you already have a Configuration Settings document for the server(s) to be configured. For Domino Release 5 and greater servers, a Configuration Settings document is required to set up SMTP routing.

2. From the Domino Administrator, click the Configuration tab and then expand the Messaging section.

3. Choose Domains, and then click Add Domain.

4. On the Basics tab, complete these fields:
FieldEnter
Domain typeChoose Global Domain
Global domain name(Optional) A word or phrase that describes the domain. Never use the name of an existing domain for your Global Domain
Global domain roleChoose one:
  • R5 Internet Domain - For Domino Release 5 and greater SMTP servers.
  • R4.x SMTP MTA - For Domino servers that use the SMTP MTA to send Internet mail.
5. Click the Restrictions tab and complete this field:
FieldEnter
Domino domains and aliasesThe Domino domain name and aliases. Domino uses the domain name and aliases when accepting mail from the alternate domains listed in the Global Domain document.
6. Click the Conversions tab, complete these fields, and then save the document:
FieldEnter
Local primary Internet domainThe primary Internet domain name that your company uses to represent themselves to the outside world -- for example, another.com.
Alternate Internet domain aliasesAdditional Internet domain names that your company uses -- for example, still.another.com, yet.another.com, have.another.com, and so on.

Use the asterisk (*) as a wildcard to represent the names of subdomains. Wildcard use is valid only if the wildcard character appears as the first character of a given entry and represents an entire subdomain name, for example: the entry *.another.com indicates that Domino treats any subdomain of "another.com" as a local domain.

Entries that use wildcards in any other way are considered invalid, including:

  • Using a wildcard in any position other than as a leading character in the entry. For example, the entries another.*, and still.*.com are not valid.
  • Using a wildcard on its own to represent an entire domain suffix. For example, the entry * is not valid.
  • Using a wildcard to represent a portion of a name only. For example, the entries *other.com and *ill.another.com are not valid.


7. Restart the server to put the changes into effect. The server reloads information in the Global Domain document into memory only after a restart.

If a Domino server uses ETRN to pull mail for multiple Internet domains from another mail host, you can set up the Connection document to that host to request mail for alternate Internet domains. Details can be found in the topic "Routing mail over transient connctions."
