I am using this setup in my postfix main.cf. [obfuscated] is my actual
key for spamhaus.

I was still getting a TON of junk from onmicrosoft.com. I blocked the
domain many months ago... Do you recommend I let that back open? I
definitely don't want to miss emails from folks who use outlook.com
(although, not gonna lie, it feels nice to raise a middle finger to
Microsoft for their terrible email practices).

I am using spamcop and spamhaus to block. There are indeed outlook.com ip

Does anyone else just block all traffic from *.onmicrosoft.com? I have
literally NEVER gotten anything from that domain which is not obvious junk.
I set up postfix to just flat out refuse anything from that domain.[1]
If I get any complaints, I may ease it up, but I was getting TONS of
spam messages from that domain and I figured it was easiest to just
block it.
