[RFCI-Discuss] DSN listing of secureserver.net

[T]

For the record, a lot of SPF configurations don't realize that HELO do
matter in th case of null <> sends and that "brain dead" behavior is
actually probably per spec and totally correct.

That sorta means, you probably have not configured the SPF records for
the hostnames you use in your HELO greets so the problem is probably
entirely your fault sorry to say, but a lot of domains are like that.


While for the longest time, it thought it annoying that all hotmail
servers used "hotmail.com" in their HELOs not quite to the spirt of
RFCs (individual servers weren't identifiable), turns out years later
that this would make it easy for them to configure SPF records without
screwing that up.  A convenient coincidence for them.

Woops, they've screwed up it now... they switched over and now use
proper hostnames. like...

EHLO bay0-omc2-s33.bay0.hotmail.com
EHLO bay0-omc1-s28.bay0.hotmail.com
EHLO bay0-omc2-s10.bay0.hotmail.com

So guess, what, they don't have SPF records configured for those.
Haha... so they did screw things up after all.  Haha, so funny.


The moral of this story, or of the original story (this thread) is...
if you have mail server, configure SPF records for you hostnames too.
The moral of the hotmail story is they can't get anything right.
