Hi, I would like to redirect the smtp port (25) in a VPS server running ISPConfig3 as a mail server to another port (say 26) in the home server running ISPconfig3 with all services. Mail<----------> Via VPS (port25) <----------> to Home Server (port26)-- the final storage of mails. Is there a way to do so without breaking ISPconfig3 without using smtp port redirection providers?*** Input appreciated. Thanks! /z *** Something like this but on your own: https://www.dnsexit.com/Direct.sv?cmd=mailRelay
> try to enter in the relay server field in server config settings: my.targetserver.tld:26 Thanks @till for your prompt response. §1 And there are "RelayHost user" and "RelayHost password" fields, are they required to be filled-in? If so, what user and password is it referring to? §2 Do I need to reconfigure the destination mail server, too?
You can leave the user and password empty, if the relay-server (your home server) accepts the mail from the server. With postfix just add the ip from your vps to mynetworks and reload postfix.
