You're not listed, so it's not a listing. A listing would cause a 550
bounce at the SMTP transaction with more details.
What is happening is that something in the message is being
fingerprinted. They use Proofpoint as their main filter, so it's likely
their content scanners are not happy with.
They also likely see very low volume, so they don't have enough history
to make a decision on whether to contest the fingerprint or not.
I do know that when a sender moves your email to the inbox, that will
create a whitelist entry for that sender.

Hi all,
after years of operating this exact mailserver for personal use and some
hobby projects here and there with https://hetzner.cloud/
<https://hetzner.cloud/> on the IPv4 157.90.168.125, I noticed that
everything from it still goes to spam with @icloud.com addresses. This
e-mail service is not very popular with Europeans and I hardly ever send
an e-mail to it.
However, unlike even Microsoft, they unfortunately seem to have no
process of delisting the IP at all:
Hello,
Thank you for your message.
iCloud Mail uses reputation systems, user feedback, and other
dynamic filtering technology to route or reject inbound messages to
our users. If you are consistently seeing your messages routed to
the Junk folder, please visit our postmaster support article at

<https://support.apple.com/en-us/HT204137> for information on our
recommended best practices for bulk mailers.
Please note that messages from new sending IP addresses or domains
may experience fluctuations in deliverability performance till a
more established reputation is established for the sender. In
addition, messages to deliverability accounts are not indicative of
actual performance of a sender’s campaign.
Best regards,

Do you have any ideas apart from using a relay like SES or artificially
increasing my e-mail count to them?
Thanks
Max
