I'm sorry. I will be careful.
Thank you for your reply despite difficulty reading.

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.
Thank you.
