I dont Think anybody understands. A domino server does not route mail id annoter serve contacts it for replication.
Try to read my post. There is only a port open one Way on 1352

The hole point og my idea is that the port is not open, so why does everybody suggest that its a easy thing to open the port. The port 1352 is not open from outside only inside.

So All of your suggestions does not work because a domino server delivers mail. I does not collectief. And that is What i want it to dó.

I properly have to explain it to the lab at next lotusphere

I am aware of all these tricks. And i Mean tricks. It is not logic that you have to disable the router when you want to fix something about mail.

I just want an option, like other options.

I can't be the only one in the world that have this problem, and don't want to do ninja tricks to get things to work

Yes you can do that. But for many companies this is not a option. No ports are allowed open from outside. No problem for replication, because the inside server initializes it But mail wong work
