I have never said anything about silent rejection. SMTP message

"550 5.7.1 Spam Refused"

is NOT a silent rejection - it is a VERBOSE rejection by (e.g. my) mail
server, and sending (e.g. your) mailserver is supposed to construct DSN to
the sender (e.g. you).

If your mailserver does not construct the bounce or drops it, it is NOT my
fault because my mail server has verbosely refused to take the message.


It's even much more likely that this message will get to the sender than if
my mail server accepted such mail and sent a bounce, because many bounces
are spammy and many spam filters are likely to drop bounces, especially
those received from remote servers.

If this is what you are angry at, you are whining at wrong side, rejecting
mail is correct, not sending or droping bounce is what's wrong and it
happens on senders side.

And it's the rejection equivalent to "550 5.7.1 Spam Refused", instead of
bounce, which can be compared to another envelope with part of original mail
stuck inside.


Your rant is completely useless.

see above. What you are blaming us for, is the proper way to reject e-mail.

If some dropping happens, it happens at different stage which outside of
receiving server's scope.

I will repeat that,  if you send mail through your MSP, and the mail gets
rejected by remote mail server, it's your MSP's job to properly notify you
about the mail being rejected.

If it does not, it's your MSP's fault.

If your MSP delivered the mail to remote mailserver and the remote server
would create a bounce, then it would be your MSP's job to deliver bounce to you.
However, your MSP likely drops many of bounces sent to your addresses as
result of mail forgeries, which you certainly don't want to receive, and the
mentioned bounce may be dropped.

If it is dropped, it's your MSP's "fault".

I have even encountered complaints about mail sent via remote MSP's (not the
one that would receive mail) and then not getting the bounce (because
receiving MSP expectedly considered the bounce to be spammy).

Simply said, if you want to receive a DSN, you must cooperate with your MSP
and avoid sending mail through other MSPs to avoid useless bounces.

Rejections are not the problem here. It's just the opposite: accepting mail
and then sending a bounce is what causes the loss.  And in both cases the
loss happens on se3nding MSPs side.

Few? No, more like 20 years ago, when spam became a huge problem. If a message 
is spammy or contains dangerous attachments, it is discarded. The user targeted 
with the attack will never know. This is because this is what users WANT.

Also, it is *my* mail server. My hardware. My bandwidth. I can do whatever I 
want with it. If users do not like what I am doing, they are free to get 
services elsewhere. I've had users "insist" that I allow MS Office files in 
attachments. I've informed them otherwise.

The VAST majority of senders are fraudulent.

If the message is discovered to be unwanted before it is delivered, the sender 
(the REAL sender) gets a notification the email wasn't accepted. If the message 
isn't discovered to be unwanted until after it is accepted, then discarding is 
the only possible action.

The world is an imperfect place. Emails fall out all the time.

I know of no mail service that will allow unfiltered mail. I mean, maybe they 
exist, but I seriously doubt it. *I* would never use one myself.

Stop thinking that silently rejecting an email isn't the same

You are blaming us for how internet communication works for years.

Until the past few years, email that was sent to me
was either received by me or the sender got a rejection message.


Your rant is completely useless.

The former tells the sender there was a problem delivering 
the email -- usually accompanied by the type of error.


In the former case, the sender knows something is
refusing to deliver the email and knows the sender didn't get
it.  In the latter case, the sender "expects" that the user
is likely to have received it (because there was no message
send back that there was a problem delivering it).

If the sender gets a rejected message, they can
tell the listed-recipient that the email was rejected and
to please correct the problem.  If they don't get anything
back, they won't even know what is wrong with the email
should they want to resend it.

To compound the issue, the recipient may not know
their email is being filtered since they asked for it NOT to be.

That their own mail-provider is the one doing the dropping after
that provider gave the impression that filtering was an option
to be turned off/on in the user-control-panel, and that
they had chosen "no filtering" is likely to be a bit miffed.


Since the user knows the incoming email wasn't spam
(after looking at the group archives), whether or not
it was rejected or dropped is a bit moot at that point.
