because this is like waiting 1h for email delivery..
No, your "mail" is delivered. Its just not confirmed yet.
uhh ok, so the
mail is delivered, but I'm unable to read to content and have to wait unknown time, because lot of guys sending mails.. (btw, yesterday I have to wait 5 hours and 28 minutes for first confirmation)
..if you don't feel this like a problem, believe or not, but it IS problem.
More like you can't prove who sent the email for unknown time. Which is actually true, since email is basically always insecure.
A better analogy would be credit card transactions. Those take 6 months to confirm.
