Understanding E-Mail Address Policies

Creating E-Mail Address Policies

When creating an e-mail address policy, you can use the following e-mail address types:

  • Precanned SMTP e-mail addressPrecanned SMTP e-mail addresses are commonly used e-mail address types provided for you.
  • Custom SMTP e-mail address. If you don’t want to use one of the precanned SMTP e-mail addresses, you can specify a custom SMTP e-mail address.
    When creating a custom SMTP e-mail address, you can use the variables in the following table to specify alternate values for the local part of the e-mail address.

    Custom SMTP e-mail 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 = 2, the first two letters of the surname are used.
    %xg Uses the first x letters of the given name. For example, if = 2, the first two letters of the given name are used.
  • Non-SMTP e-mail address. The following types of non-SMTP e-mail 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)
    In Exchange, all non-SMTP e-mail addresses are considered custom addresses. Exchange doesn’t provide unique dialog boxes or property pages for X.400, GroupWise, or Lotus Notes e-mail address types. If you add a non-SMTP custom e-mail 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 e-mail address policy. The following error will be logged in Event Viewer: “The e-mail address description object in the Microsoft Exchange directory for the ‘SADF’ address type on ‘i386’ machines are missing.”

    Rajesh, what if I want to customize an address like this:

    I’m using the alias variable followed by an underscore and 3 random letters. Will that work? I tried it but the email policy doesn’t apply and I get an error returned by the address list.
