Thanks for quick reply.
But I still can't understand why the smtp communication always should be the same.
I wil try to explain my problem.
I am recieving mail on port 25 at our firewall (gateway).
I have to point to a SMTP server for delivering the smtp post.
Normaly I point to my mail server (Groupwise on LAN).
But if I want to use PROXMOX, I have to deliver the smtp to PROXMOX instead.
The Proxmox must act as a Relay to my old mail-server,
and if the proxmox should act as an outbound smtp scanner I have to setup groupwise to deliver smtp outbound mail to proxmox.
The Last thing I can't figure out (on groupwise)!!!
That's all
Hope you understand.
Best regards
