If you're using GreyListing, know that a given email will not be
coming from the same IP address twice.
The outgoing IP address is randomized for ... reasons.
I substitute "no".
That is absolutely ignorant to tell the people that you do mail in a
broken way and tell them it is for a reason, you don't want to tell.
Sharing an outbound queue amongst many different machines is not
"broken" in any way. There may or may not be rock-solid simple
explanations for *WHY* that approach was chosen, but it is entirely a
local issue of purely local concern. There is no RFC asserting that
retries after a transient rejection should come from the same cliuent
IP.
Greylisting, in contrast, is designed as breakage. It is breakage that
is handled well by the most common behaviors of small to medium sized
sending systems, but those behaviors are purely a matter of convenience.
Greylisting is an intrinsically heuristic practice, because you need to
adapt it to what works rather than having some standard spec that you
can count on interoperating.
On the same time being one of the biggest spam provider.
Which is a direct consequence of what they've done to become the biggest
commercial mailbox provider.
Microsoft has no history of doing what non-paying non-customers think
they should do, especially if it possible for them to perceive such
deadbeats to be competitors. If you run a mail server, Microsoft will at
some point treat you as a competitor rather than as a partner. Do not
expect anything else.
