Look at this line.

And look at this line.

And then look at this.

You've changed something for this to happen. This is what you would get
from making a telnet connection to an SSH server. You shouldn't get
that from Postfix.

There is a problem with the connection, and it's not a mail problem.
You have ssh listening on port 25. Change it back to port 22, or some
other port, and Postfix will be able to use port 25 for external
connections.

Yes I was following instructions from houghi, to test if the port was open.

Kind Regards,

I missed that part of Houghis suggestions. Glad it's working now.
