Force external routing to send emails to internal recipients


Hello, I’ve installed a nethserver to manage our PEC mailboxes.
We have more domains and companies in our organization, so they have to send some PEC emails to each other.
I use stunnel to route each smtp sender to Aruba smtp (port 465).
If I send a PEC to another recipient who exists in my nethserver, email arrives correctly but using the internal routing, without any legal notification who is required with PEC.

Is it possibile to force external smtp to route all messages (also if they are sent to internal recipients?)

Thank you.


welcome to NethServer Community,

I think it could work by using a smarthost. Check out following howto:
