And also what my spamassassin is saying about mails to my users from other people who have dialup IPs and "incorrect" smtp servers. I can't add all their server to my trusted_networks.
Stop mis-reading my message.
Stop reading into the meaning of trusted_networks... Read exactly what I told you to do.
At NO time did I EVER suggest you had to add an ISPs mailserver to your config... I even explicitly told you NOT TO!
I tried VERY hard to make it clear that you don't need to add other servers. ONLY yours... this fixes the bug for your machine entirely.
You NEVER have to add a ISP's server to your trusted_networks.... NEVER NEVER NEVER NEVER.
if xanadu trusts xanadu, it will stop mis-marking mail from comcast, aol, sprint, and every other dialup ISP in the entire world.
Read my message again, read it correctly, and without making assumptions.
