As with the current whitelist mechanism, you will be able to
add blacklist entries by saying "MANY" instead of "OK" or "OK2".

I'd not thought of the envelope HELO string, because it is not a header.
I don't see occurances of "TmpStr" in the spam in my logs, but I do
seen enough "localhost" and "localhost.localdomain" to make it worth
considering.  I'll see what I can do.
Of course, this would only be available for dccm, since there is
no reliable way to get the HELO value to dccproc, except in cases
where it would probably be quicker and easier to match the HELO
value directly.
