So you\'re not adding the Return-Path at delivery time?
But I have never sent any email to domain softbank.ne.jp...
That is irrelevant.
The Return-Path header you are trying to match is very likely
not in the mail as received by postfix, but rather added when
the mail is delivered to your mailbox.
And anyway, rejected mail with the null sender address is the
wrong approach (maybe justified as a TEMPORARY measure when
receiving huge volume of backscatter messages addressed to
legit users).
For some suggestions on dealing with incoming backscatter,
please see:
