I think without you would have, just with extra error messages
that http codepath filters out.

Here you do the same as the code would for HTTP 404 when you get
550 _and_ RETR failure...

... but you say, while the original code says "declare error if
it is not HTTP 404", "oh by the way, if it is 550 _or_ if it
is RETR failure then do not trigger this if()".  I suspect you
meant to say this?

	    (slot->http_code != 550 ||
	     slot->curl_result != CURLE_FTP_COULDNT_RETR_FILE)) {
