@usmannasir I have a problem with my Email Server. By default, my ISP does not release port 25 and I have tried all methods and they do not release it. Then in the Snappy admin I changed the port from 25 to 587 but even with SMTP with port 587 I still don’t receive or send emails! What could be happening? Below I will share some logs that I have.
@usmannasir I did this, as I mentioned earlier port 857 was added in snappymail. But I still can’t receive or send emails, do I need to modify the port in Postfix?
Well, I already tried this and changed the pta 587 port as mentioned, but when I check the Postfix logs I get this.

The first check by any mail system is on port 25 and as you shared the cheklts results when port 25 is blocked then checktls will not give you any response because checktls only check port 25.
More if you can please open a ticket i can try to use other port and i can try to fix things for you.
got it needed some information you already share a lot but i need one more thing please provide that
