Wietse Thank you for your reply.
Because I am not able to understand much about the following because of lack of study, Can you explain it in a bit more detail? Please. > To recognize an email address, Postfix compares the content of two > character strings stored as a sequence of octets. > string contains "double-bounce" and the other contains informatiom > from an email address that resolves to the local domain (matches > mydestination or inet_interfaces). What is "two character strings"? Does Postfix usually store "two character strings"? Addresses are verified by injecting probe messages into the Postfix queue.Is the queue manager "double bounce address" detect "double bounce", and discard it? Is "double-bounce address" pointing to "double-bounce@$myorigin"? I will wait for your reply. Thank you very much. 2019年2月15日(金) 21:08 Wietse Venema <wie...@porcupine.org>: > natsu: > > 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.
