Is it possible to send an email "backdated"?

Question

Mail server

Good afternoon.

You need to send a letter from three months ago. So that the "incoming" date matches the date the letter was sent. I understand that the SMTP server puts the real "incoming" date.

Maybe there are some solutions? A matter of life and death, literally.

If anyone can help, write. I think we can agree.

Answer 1

No way. Each server along the route adds a record with the date and time it received the email.

Answer 2

In the source, the dates are visible not only on the sender's server, but also on the recipient's server, so, alas, this is impossible, even if you can somehow change the date on the sending server.

Answer 3

If you are the admin of the server on which the user is sitting, you can edit the letter directly in his mailbox. It will not necessarily be easy, but if the letters are not encrypted, then a hex editor.
Otherwise, no way.

Answer 4

No. The date is put:
- in the sender's server log
- in the recipient's server log
(as well as in the logs of all transit servers, if any)
- in the message header
That is, you need to be an admin of all of the above in order to be able to correct the logs and headers. Why edit logs? With a "matter of life and death" they can easily be requested :)

Answer 5

And the point is if the person who receives it wakes up to write the date when the email came to the server of his mail service. You can write in the header when you send, but this will not work

Answer 6

This is possible, but not in all cases. Many (most?) email programs display the date from the Date header, it's easy enough to fake it. However, the web interfaces of popular mail services display the date of receipt of the letter.
In the headers that add mail servers, the date of receipt of the letter will be visible in any case.
