Removing the initial quote without changing anything else allows it to be posted
Removing the word "the" without changing anything else allows it to be posted
Removing either the word "subject" or the word "to" without changing anything else allows it to be posted

And now I've found something even more bizarre . . .

If I place it later in the text it will spellcheck and post without error.
