Hello Let me question about double bounce.
I am using postfix 2.10. For double bounce, the document is too few to understand the behavior of double bounce. I confirmed the following documents. There is a point I do not understand, please let me ask a question. Postfix Address Verification Howtohttp:// www.postfix.org/ADDRESS_VERIFICATION_README.html 1.About "By default, Postfix probe messages have a sender address "double-bounce@$myorigin" " What is "probe messages"? I do not know what the survey message in the mail is. 2. About "Postfix always discards mail to the double-bounce address" By default, Postfix recognizes double bounce discard, is it correct? How does "double bounce address" detect "double bounce ",and discard it? I can not find the document explaining the mechanism, so could you tell me? Or is there something helpful?
