So what's the news?

Ahh, the power of an oligolopoly...

As long as you assume that you are not in a position to tell people that
Hotmail is bad, you'll be bound to be playing by Microsoft's rules.  Go
and get a Hotmail account then.

OK. I have taken your advice to the letter ;-) and I subscribed today
to MSN Premium for $20 per year! ...and... you were correct... Hotmail
is no longer broken!

I can now send mail to other Hotmail addresses using my Outlook
Express and the Hotmail HTTP server. Whatever the "From" address that
I program in my Outlook Express, Hotmail users (and others, as far as
I can see) receive my messages in their Inbox, and no longer in their
Junk Mail folder. (I did not push the trial as far as sending messages
with "Viagra" in the subject line, though.)

But what baffles me is that, when sending messages that way, I
seemingly bypass all the world's SPF filters. I have sent a test
message using as "From" address a domain that has the SPF string
"v=spf1 -all" (meaning that no mail should ever be sent from that
domain). Well, my mail arrived perfectly in Hotmail's inbox, but also
in other mail services inboxes, and (when available in the headers) it
had SPF_PASS.

The other headers were:
Return-Path: <my_id(_at_)msn(_dot_)com>
X-Originating-Email: [my_id(_at_)msn(_dot_)com]
X-Sender: my_id(_at_)msn(_dot_)com
From: "Mark Wolk" <info(_at_)my_domain(_dot_)com>

and when the receiver replies to that mail, his / her reply is
properly addressed to info(_at_)my_domain(_dot_)com (and not to 
my_id(_at_)msn(_dot_)com)

??? - I must admit I don't understand why and how it is possible, but
I suppose $20 is a small yearly ransom to pay for a business to be
able to communicate reliably with 50% of its customers.
