You just add an A record with a suitable name for your server. There's
nothing Postfix-specific about this.

Then all mail to your domain will go to that mail server. No way to change
it. This is how SMTP works:
If one or more MX RRs are found for a given name, SMTP systems MUST
NOT utilize any A RRs

I can't have MX record because the DNS server have another MX record for other

What are you trying to achieve?
There are alot of scenarios where Postfix may be used:
* "Send only" email server for your website (to give your website ability
to send emails). You never receive any emails from the outside.
* Forward only: it just accepts mails from your apps, and sends them via
