If you have been using SMTP gateway aliases to handle e-mail addresses that do not fit the default format expected by the Internet Agent or to customize users’ Internet addresses, the Gateway Alias Migration utility can convert the usernames in those gateway aliases into preferred e-mail IDs. The Preferred E-Mail ID feature was first introduced in GroupWise 6.5 and is the suggested method for overriding the current e-mail address format, as described in Section 14.7.2, Changing a User’s Internet Addressing Settings. The Gateway Alias Migration utility can also update users’ preferred Internet domain names based on their existing gateway aliases.
For usage instructions, see Section 45.3, Transitioning from SMTP Gateway Aliases to Internet Addressing.
