What you're asking for is not directly possible with RabbitMQ. It's a bit backward from how RMQ works, and how the system should be designed.
That is, you can't filter or be "selective" about which messages a given consumer receives. Ultimately, the "selective consumer" is an anti-pattern in RabbitMQ. Once a message is in a queue, a consumer listening to that queue may receive that message (depending on how many consumers are attached, etc).
The best way to handle this, in my experience, is to either change your RMQ topology and application design so that this won't be a problem (may not be possible) or to have your app know which message it sent, and ignore anything it sent.
I think the first option is better (ensure this isn't going to happen with good app / topology design), but the second option is often easier...
To do this, you can add a custom property to your message, like "publisher-id" or similar. Have your consumer code check to make sure the publisher-id of the message does not match it's own publisher-id. If it does match, ack the message without doing anymore. If it does not match, process the message normally.
