IP Literals

[Chiper69]

Hi everyone,
I am trying to add a postmaster address to my mail server that is RFC 821 compliant. I know that Exchange does not support IP Literals and have read the KB article #193316 on how to add a user@[domain] e-mail address. I followed the instructions and added a proxy address to my postmaster account however when i attempt to be removed from the Distributed Server Boycott List the status comes up with

Result:

Recipient Report:
210.50.90.50 does not like recipient.
Remote host said: 550 Requested action not taken: mailbox unavailable
Message Report:
Giving up on 210.50.90.50.
