How to stop double-bounce FROM sender in postfix

Question

I am getting huge amount of these in my mail log, and unable to find its originator. What could be the reason? Here is log entry:

postfix/cleanup[9626]: 4413082E40: message-id=<[email protected]>
postfix/qmgr[9367]: 4413082E40: from=<[email protected]>, size=255, nrcpt=1 (queue active)

Solution

The double-bounce messages are used by postfix for address verification.

Have you added or changed anything recently? If things like content_filters, or milters are not functioning correctly, you can see errors similar to this.

Can you grep out all examples of that message-id ?

@Farhan : Mmmh... looks like two different process with different purposes log the message they handle one time each. Splitting the log of "cleanup" and "qmgr" can be temporary workaround.
