Network is unreachable or connection timed out. Can I change relay hosts port from 25 to 587.? Please help

Port 25 is required. You have to either contact Oracle Cloud to open it, or switch to another cloud / vps vendor.

I went through this myself a year ago or so. Linode (now Akamai, but still branded Linode) is one of the few reputable cloud hosts i found that allow outgoing port 25.

It's disabled by default, but they have a process in which you jump through a bunch of hoops to prove it's configured correctly, and then they'll open it for you.

I solved this problem.
I use oracle email delivery service. I am using now 587 port for smtp
Thanks for the comments.
