Message 1: This message does not comply with required standards.

I have no idea.

-----

Message 2: <mail at me.com>: ...  unknown or illegal alias: username at me.com

It appears that the e-mail alias table at the destination is bad.
The e-mail alias "username" points to the mailbox "mail".
Maybe that mailbox does not exist.

-----

Message 3: Address rejected

The mailbox does not exist.

-----

Message 4: mailbox unavailable

The mailbox does not exist.
