Postfix Mail sending issue

I did the system setup successfully. All settings are okay, but in my country (Turkey) 25 ports are banned. I am trying to change the port to 587, but I have not been successful. I have tried a few suggestions regarding this in the forum, but the result has not changed. I ask you to help me in this regard. Thanks in advance.

u can run on whatever port u want, BUT the receiving server is answering on port 25

so... unblock the port or sent ur email via smtp relay

Thank you for your answer. I started work to open port 25.
