This only shows the first server to send an email to, it does not prove that a server has delivered the email to the end email-inbox of the user.suomynona.yllatot wrote: ↑Sun Jan 10, 2021 7:08 pmHere you go: https://en.wikipedia.org/wiki/MX_recordFinlandGirl wrote: ↑Sun Jan 10, 2021 5:54 pmAt the SMTP level you only know whether the next mail server has accepted the email.
You do not even necessarily know whether this was the final email server on the way.
You do not know at all whether this server has delivered the email to the end email-inbox of the user.
What is wrong with you? Is it an English comprehension issue? Or a technical comprehension? A complete lack of logical thinking?suomynona.yllatot wrote: ↑Sun Jan 10, 2021 7:08 pmThat is the complete opposite of what I said. Is it an English comprehension issue? Or a technical comprehension? End-user sender is not responsible to track the internal delivery. Nor is the SMTP sending server responsible the delivery to the end user mailbox.
Thankfully, emails and SMTP don't work on imagination. And PS. Bad analogy. This would be applicable ONLY if the landlord also owned the full postal service. In this case, the landlord also depends on the mail provider (posti) that would need to goof up.
So, if you have the delivery report, that is enough evidence to prove transmission. In the receiver's email server, let's say a corporate email server fails, that is not the fault of the sender.
In the common case where the landlord has a Gmail address, does the landlord fully own Google?
Your landlord depends either on Google or Posti in the same way for delivery.
Your assumptions like "corporate email server" also sound as if any knowledge you might have had is pretty dated, in the year 2021 own email servers are very rare for companies of any size.
