I'm sorry. I will be careful. Thank you for your reply despite difficulty reading. > the double bounce did not occur, at least not in the logs above. I would like to generate double bounce in the verification environment, but how do I do it? (I thought that double bounce would occur if sending mail with a mail address that does not exist as a sender and a recipient.) If double bounce occurs, will it be output to the log? Will not output such as "from = <double-bou...@xxxx.com>"? If nothing is output, how do you decide whether double bounce occurred? I am waiting for reply.
