Bounced from the list, or bounced on my end?  Do I need to fix
something?

I meant that, surely, the rest of you aren't Outlook users.  But maybe
you are?  ;-)

The machine through which I relay emails has a static IP that will
change only if I re-provision it.  That part is not an issue.

My point, in general, is that SPF is a poor solution that assumes a
useless-endpoints-with-crappy-mail-clients model.  It is a *bug*, not
a feature, that non-Unix end hosts are not running a local MTA, and
that end hosts that *are* running a local MTA have to go through
gyrations to relay emails through "better" hosts.
