The TLS-Policy override guide only explained how to change the policy for a single destination. Where a firewall with SMTP inspection or an intercepting relay removes STARTTLS from the EHLO response, no per-domain entry helps and mail piles up in the queue. Add a section to the English and German guide describing the extra.cf overrides that drop the postfix-tlspol socketmap and fall back to opportunistic TLS, including the scope of the change and the security implications.
