How to enforce TLS negotiation for any SMTP traffic?

Fred12 9 months ago

Hello,

as from here I can configure "Require sender email domains" to enforce TLS negotiation (whitelisting). Beside this I can configure "Skip TLS negotiation" (blacklisting).

For compliance and legal reason I need to configure TLS negotiation as default for any domain. How would that be possible?

It was never implemented into the sub system here. Central Email supports this feature per default, as it does not allow non TLS at all.

Add the Internetv4 Objects, which will add all IPs for Enforce TLS.

Thanks, but any means also IPv6.
For what reason you not make just make "any" available in here as you have in firewall rules?
