Post How to use an external mailserver within ISPConfig?

I have another mailserver on a different location.
I want that all the users of a certain domain use an external mailserver at an other location.
How can i do this within ISPConfig?
I know it is possible to select the option "Extern Mailserver" in the ISP-site module within ISPConfig.
But i do not understand how this works.. Is it not necessary to specifify an new IP-address of the External mailserver?

Please let me know.

I think that when you specify an external mail server, you will need to specify the server address in the config file for postfix.

No, if I understand well the question, I think you need to set the MX record to the external server IP address in the DNS manager

The "External Mailserver" option in ISPConfig prevents ISPConfig to write email addresses for that domain into the Postfix configuration, which means Postfix will not accept emails for that email addresses anymore. If Postfix receives an email for such an address, it will relay the mail to the mail server that is specified in the MX record of that domain - which means you must have an appropriate MX record for the domain.

Hi Falco, ive also read this, i think ive a similar problem:
also im using external mailserver via ispconfig (2), when i open /etc/postfix/local-host-names i have also all !! domains which are using an external mailserver, my problem is that some users have a cms which try to send via localhost to "local" users , mails dont arrive on the right system, how can i static remove the unwanted domains from the localhostnames?

kindest regards
Jerry
