[email protected], for whom?

Question

Email

The question is almost rhetorical, but still interesting.
What smart guy and why came up with writing from the [email protected] address and indicating "do not reply to this letter"?
Why can't bots write on behalf of a working e-mail?
Why can't I reply to automatic emails, but have to search for an existing address, copy a bot's email, etc. if I want to ask a question on the received e-mail?
This is complete disrespect for the recipient, read to the client.
And almost everyone suffers from this - from little things to Google.

Answer 1

What kind of feedback via mail can be received on a letter from some forum with a link to new comments in the topic, for example?
There are many cases where there can be no adequate response from the user by mail in principle, and in order to remove questions from the strangest users, it can be useful to explain directly in the from field that no response is expected, and it will not be read by anyone .

Answer 2

Maybe because you can have an auto-reply - total disrespect to the sender :) And you send to [email protected], it sends you that we don't read, etc. And someone in this chain rubs or does not make service headers, making it clear to the MTA that the letter is making the second round. Therefore, it is better that he did not send anything.
Further, bots can write from work email and seem to often do so. Sometimes the address is unique, such as client.[id].[msg-123].[code-456789]@test.com and then the client, answering it, will send a message to some kind of feed, correspondence of the internal system.

Answer 3

What is written in the From: header may not have anything to do with the address to which you will write by clicking "Reply". The latter can be specified in the Reply-to header:
Reasons to send (show you) something like [email protected] might be a wagon. Some of them have already been written to you.
Another may be the specifics of the work of mailing services, when a certain domain is required in the From: field in order to pass the DKIM digital signature verification, but does not imply giving you the opportunity to write to the address used.
