Postfix Port Change
I have an Ubuntu server with Postfix that I am trying to send mail out on. My ISP is blocking port 25. I would like to change the port Postfix sends out on from 25 to either 465 or 587. I have tried several solutions I found on Google as well as a bunch on EE with no luck. I always get an error of either a connection timeout or deferred or delivery temporarily suspended:
connect to gmail-smtp-in.l.google.com [173.194.1 99.27]:25: Connection timed out
relay=none, delay=0.17, delays=0.11/0/0/0.06, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to $ct to alt4.gmail-smtp-in.l.googl e.com[64.2 33.186.26] :25: Connection timed out)
relay=none, delay=1930, delays=1780/0.01/150/0, dsn=4.4.1, status=deferred (connect to alt4.gmail-smtp-in.l.googl e.com$le.c om[64.233. 186.26]:25 : Connection timed out)
All appearing to be trying to send via port 25.
Could someone please show me the correct way to configure postfix to send out on different port #'s and not port 25?
Thank you!

Any thoughts on how to use port 465 and disable it from sending on port 25?

I am not looking to use any service as a relay, just trying to figure out how to change the port.
You can edit the file below:
/etc/postfix/master.cf
Find the line (usually the first uncommented line) that reads:
smtp inet n - n - - smtpd
And change it to this:
465 inet n - n - - smtpd
Then restart postfix:
systemctl restart postfix.service
You can check the port with the following command:
netstat -tanp | grep 465
/etc/postfix/master.cf
Find the line (usually the first uncommented line) that reads:
smtp inet n - n - - smtpd
And change it to this:
465 inet n - n - - smtpd
Then restart postfix:
systemctl restart postfix.service
You can check the port with the following command:
netstat -tanp | grep 465

Still gives the same error:

Thank you for your help!
Perhaps you have another issue.
Have you tried sending the mail to a non gmail account?

Yes I have to another email address, get the same error:

Notice at the end of the IP address it shows port 25. That is what I don't get, no matter what change I do in master.cf that port number never changes.
