dfw-datacenter.com aka Tailor Made Servers aka tailoredservers.com. I
can see why Hotmail has that blocked. Lots of spam to traps out of
that /19
But if you look at that range here:
https://talosintelligence.com/reputation_center/lookup?search=67.222.128.0%2F19
...then sort by IP reputation, with the best reputations listed at the
top, there is a significant amount of "green" and then a significant
amount of "yellow" - BEFORE you get to the "red".
I'm not saying that a little collateral damage isn't warranted on
occasion - but I've seen too many times where, this past year or so,
hotmail/outlook's spam filtering (but NOT O365!) went "too draconian" -
and that is ironic considering how much egregious spam comes from
microsoft's IP space. For example, a large portion of those egregious
bitcoin extortion spams come from their IPs. In some cases this past
year, hotmail/outlook PERMANENTLY banned normally legit senders that had
a short term security problem that was solved. These were situations
where MUCH legit email started getting routinely blocked. If I did stuff
like that with my invaluement anti-spam blacklist...permanent "FU"
listings - I'd lose almost all my subscribers - and I'd be laughed at
by the internet security industry. But it's OK when a large 800-pound
Silicon Valley gorilla does it, right?
(iow - this comes across to me as hypocritical bullying)
