I was merely pointing out that in one place you have:

	(http_code == 550 && result == ERETR)

and another place that tries to say the opposite you have:

	(http_code != 550 && result != ERETR)

which is not the same thing as

	!(http_code == 550 && result == ERETR)

I understood, from the former "Use alternates if necessary"
part, that you wanted to make sure that 550 is really from
FTP_RETR and not other random HTTP error message, and I think
that is a reasonable thing to do.
