    IBM agrees with this request and is still using it as input to the planning process. However, at this time it is not committed to our plan. This request will be updated in the future if IBM implements it.

    Both functions are needed:
    1. email domain name required to support IDN!
    2. Email prefix ( the left characters of the @ symbol in the email address) required to have IDN support!

    IDN requires a lot of update to existing email system. 4 Request for Comments (RFC) were created by Internet Engineering Task Force(IETF) for the IDN:
    1. RFC 6530: Overview and Framework for Internationalized Email
    2. RFC 6531: SMTP Extension for Internationalized Email
    3. RFC 6532: Internationalized Email Headers
    4. RFC 6533: Internationalized Delivery Status and Disposition Notifications

    We need evaluate what can be added to IBM i SMTP email system and when.

    To help prioritizing the IDN support, can you describe what IDN features are used in your business environment?
    1. Is the email domain name required to support IDN ?
    2. Is the email prefix ( the left characters of the @ symbol in the email address) required to have IDN support?
