Yes, that's what I said, no "error" as far as SPF HELO
checks are concerned (in Wayne's drafts up to RFC 4408).

I don't think so.  An a:%{h} after "HELO museum" should
match the IP of TLD "museum".  While the HELO is an SMTP
syntax error it's otherwise a host with an IP, if you'd
try `host museum` or `nslookup -q=a museum.` you'll find
an IP.

Good.

Yeah, a bug while trying to implement draft-lentczner :-)

Please add also the a:%{h} cases after "HELO museum" or
"HELO museum." (of course s/museum/test/ or similar, for
a match of its IP), it's not the same as "oemcomputer".
