When creating an email address policy, you can use the following email address types:

  • Precanned SMTP email address. Precanned SMTP email addresses are commonly used email address types that are provided for you.

  • Custom SMTP email address. If you don't want to use one of the precanned SMTP email addresses, you can specify a custom SMTP email address.

    When creating a custom SMTP email address, you can use the variables in the following table to specify alternate values for the local part of the email address.

     

    Variable Value

    %g

    Given name (first name)

    %i

    Middle initial

    %s

    Surname (last name)

    %d

    Display name

    %m

    Exchange alias

    %xs

    Uses the first x letters of the surname. For example, if x = 2, the first two letters of the surname are used.

    %xg

    Uses the first x letters of the given name. For example, if x = 2, the first two letters of the given name are used.

  • Non-SMTP email address. The following types of non-SMTP email addresses are supported:

    • EX (Legacy DN Proxy Address Prefix DisplayName)

    • X.500

    • X.400

    • MSMail

    • CcMail

    • Lotus Notes

    • Novell GroupWise

    • Exchange Unified Messaging proxy address (EUM proxy address)

    importantImportant:
    In Exchange, all non-SMTP email addresses are considered custom addresses. Exchange doesn't provide unique dialog boxes or property pages for X.400, GroupWise, or Lotus Notes email address types. If you add a non-SMTP custom email address, you must have the appropriate dynamic-link library (DLL) files. If you don't provide the appropriate DLL files, you won't be able to create a customized email address policy. The following error will be logged in Event Viewer: "The email address description object in the Microsoft Exchange directory for the 'SADF' address type on 'i386' machines are missing."
