Setting a domain masquerade in Exchange server 2003

  • Open the Exhange System Manager program
    • click/choose Servers
      • [servername]
      • Protocols
      • SMTP
      • Default SMTP Virtual Server [unless you’ve setup another one that you’re using]
      • right-click and choose Properties
      • Delivery
      • Advanced
      • under “Masquerade domain,” type in the domain name you want showing up on the recipients’ end, instead of the Fully-qualified domain name that’s shown in the next field
        • e.g., “” instead of “[servername].[windowsdomain]”
      • for added security, you can check “Perform reverse DNS look on incoming messages,” if you don’t mind the extra traffic and delay involved
