My measure has nothing to do with email addresses.  Only the HELO/EHLO
argument.   I'm asking that if you are not going to conform to the 
standards of the net, please relay your mail through a host that does
and does not mind you not doing so (use your local ISP's mail server
as a smart host)

I did discover my NAT/router was getting blocked by the filter when it
tried to send me alerts ( ... "hey!   here's a spoofing attempt from
IP x.y.z.t on the WAN" ... )  So I added that IP to the exemption list
for the drip milter  (-x xx.yy.zz.tt/32).

True.  I'm a bit of a sendmail snob, but that's mostly because I can
beat it into submission (regardless of what that stupidity I need to
make it do... can you say "99 bottles of beer" in .cf?   I can... 8^)

For now, I'm still getting all the mail being submitted to me by
"real" MTAs (as opposed to spamware/malware).  That's due to my
dripmilter returning the error on the MAIL FROM:, not the RCPT TO:.

So, the mail fails over to my backup MS host...  And I'm seeing a
LOT more mail coming from him that I used to.

The proof in the pudding is to count how much "legitimate" mail is 
how showing that host in the Received headers.

(Just what I need... another task to do...)
