I'm sorry but I fail to understand what value is your acid question bringing to the conversation.
FWIW, Mathus, the remote side is simply printing a 5xx one line message "not accepted" banner instead of the expected welcome 220 banner, not giving any explanation to why, then closing the tcp session, without postfix even getting a chance to say HELO! However, the topic of this thread is: Can postfix retry a failed message, by attempting to retransmit using a different outgoing IP address of the machine it's running on? If I send a mail to the same destination using the old IP address, a regular smtp conversation takes place and email is accepted by the remote side!
