external postfix mail server

[marmellata]

Hello, I'm new to directadmin. I got a mail server working inside my lan to manage my accounts locally. Now how can I configure my isp directadmin (my isp gave me access to it) not to manage my mail accounts locally (on their server) but to forward everything to the mail server inside my lan?

thanks
