I am trying to configure postfix to disable TLS for a specific remote smtp server that serves for multiple recipient domains.
I have set up a policy map that already contains some entries for specific recipient domains that work fine. But ist there a way to configure postfix to disable TLS for a remote smtp server regardless of what domains are hosted there?
I have tried quite a few entries in my TLS policy map file but without any success. I tried:
- smtp.server.com none
- [smtp.server.com] none
- smtp.server.com:25 none
- [smtp.server.com]:25 none
- 18.104.22.168 none
- [22.214.171.124] none
- 126.96.36.199:25 none
- [188.8.131.52]:25 none
btw: yes, I postmapped the modified policy file :)
Still postfix tries to relay to that host using a TLS connection. As soon as I configure a specific recipient domain delivered via this mx, things work fine and no TLS connection is established. But since there are hundreds of recipient domains on the remote host, I cannot configure all of them in my policy :)
Any suggestions? Thanks in advance!
