your mail is quite hard to read.
it would be great to use mail client that does not random spaces around
dashes, slashes, equal signs etc. and even to queue IDs.
... and does not wrap log lines.
Let me question about single bounce and double bounce.
ยท About single bounce
Sending to a mail address that does not exist results in a single bounce.
The single bounce was recorded in the mail log as shown below.
The sender address is empty ("from = <>"), I realize this is a
specification, is it correct?
yes
Do you want to discard single bounce by default?
yes. They are designed so to avoid endeless mail loops.
Feb 20 15:59:34 hoge postfix / local [4102]: B 9 B 3628 D 539: to = <
r...@example.com>, relay = local, delay = 0.02, delays = 0 / 0.01 / 0 /
0.01, dsn = 2.0.0 , status = sent (delivered to maildir)
horrible...
I thought that double bounce would be generated by sending mail with a mail
address that does not exist as a sender and destination, but the following
log was output.
Feb 20 16:21:01 hoge postfix/pickup[3714]: 023B228D536: uid=0 from=<
hog...@hoge1.example.com>
this is the original mail

nrcpt=1 (queue active)

Feb 20 16:21:01 hoge postfix/qmgr[3715]: 023B228D536: removed
Feb 20 16:21:01 hoge postfix/local[4340]: 0581728D539: to=<
hog...@hoge1.example.com>, relay=local, delay=0, delays=0/0/0/0, dsn=5.1.1,
status=bounced (unknown user: "hoge11")
and this is the bounce from <> to original sender.
When double bounce occurred, I thought that "from = <double- bou...@xxxx.com>"
would be output, but as far as I confirmed it was "from = <>". If double
bounce occurs, will not "from = <double-bou...@xxxx.com>" appear?
the double bounce did not occur, at least not in the logs above.
