The issue here is one of an email that has been "lost in cyberspace." The receiver is claiming never to have received it. However, I recieved an automated out-of-office reply as a response to my email. They are now saying that my original message never even landed in the recipient's inbox since the mail server's spam system must have blocked it.
It seems odd to me that a mail server would allow such an out-of-office reply to a message that it at the same time deems to be spam. Is this a correct assumption?
