Thanks. Unfortunately, at this time upgrading is not an option (long

(hopefully) but in the mean time I badly need a solution now. As I said
enforced TLS is not possible but I do need at least opportunistic TLS.
I think the main.cf settings you need are
smtp_use_tls = yes
smtp_enforce_tls = no
No warranty expressed or implied.
If that doesn't work, you'll need to consult the documentation
included with the third-party patch that provides TLS support
in your version of postfix.
