I want/need to set up ISPconfig 18.104.22.168 server 1 in the Netherlands, ISPconfig server 2 in Germany. Number 2 will also be the mailserver for 1 and 2, because at mailserver 1 port 25 is locked by ISP for relaying. And I mean really locked no workarounds found yet. First of all, will this work or is this setup still using port 25 and wil it be locked for relaying once again? So my questions are: what will be the origin of the mail sent from the Netherlands, wil this be the Dutch IP or the German IP? How do I set up number 2 in Germany so it understands it has to sent all mail? I assume the mailserver defined in the Netherlands in ISPconfig will be the IP adres of number 2 in Germany?
