we are running a small smtp relay service with postfix for authenticated

I can't believe I just looked up MS docs for you, but:
https://docs.microsoft.com/en-us/powershell/module/exchange/mail-flow/set-sendconnector?view=exchange-ps
Note the -SmartHostAuthMechanism and -AuthenticationCredential parameters.
For more info please ask in a forum appropriate to o365 or exchange,
this is not support for exchange.
