Will SPF be able to help to detect these kind of forgeries?

Hi,

I got this bounced back message from AOL. Obviously, its a ratware
sending email as my domain's forged address. It seems that the first
"Recieved:" line is completely forged.

Co-incidentally, this header doesn't have the "Return-path:" header
at all.

Question: if AOL had SPF implemented (current SPF clients) at their
relay servers, would the SPF client be able to detect this or it
would simply quit 'cause there is no HELO or EHLO in the headers?

Although, according to section 2.2.1 of draft-mengwong-spf-01.txt
clearly says that SPF will just terminate with "unknown" error when
it can't find any FQDN in the HELO argument.

Question (again): so, is it wise to drop any email that does not have
HELO or EHLO argument? Or, there are valid cases of missing HELO or
EHLO in headers of legit emails?

Pardon me if this was discussed in the list before.
