we hat our own mail relay which is hosted on an external cloud server.
To handle the personal mail boxes we are using Kopano, which is located in our internal network.
To communicte with our clients we use a ticket system which stays in our DMZ.
Both systems use the same domain “ourdomain”.
We cannot send mails from the personal mailbox to the ticket sytem, as kopano is configured to be resposible for our (complete) domain.
Is it possible to configure Kopano to send any mail for “ourdomain” that it has no mailbox for to our external mail relay, which would store them for the ticket system to pick them up?
