I have DKIM, SPF, etc. but still gets caught by spam. What do you mean by "trusted host"?

An email provider that is not blacklisted and allows relay. I currently use my ISP for that.

Taken from my smtpd.conf:

  table secrets { mylogin = [email]@ziggo.nl:[pass] }
  accept tagged DKIM for any relay via tls+auth://mylogin@smtp.ziggo.nl:587 auth <secrets>
Oh, I see, thanks!

It kind of defeats the purpose, since now the third-party will be able to read all my outgoing emails, and have control over them.

You're transiting over their network anyway -- the jig is already up even without relaying via their gateway.
Connecting directly to the remote (non-ISP) mailserver with TLS shouldn't reveal any message contents.

Relaying via the ISP's mail server though (even with TLS) seems like it would disclose the message contents.

Is DMARC included in your 'etc'? I think thats needed for gmail these days. If rdns, dkim, spf and dmarc are there, try checking your IPs reputation (senderscore) that could be it.
