postfix connection is timing out? trying to send email to my yahoo or gmail address?

[cyberdome]

I have installed Postfix using Yum, I am running Fedora 20.

yum install postfix.

I setup the postfix main.cf file. I believe I have done everything correctly, Please, can someone guide me to right direction. Am I missing something. I think My ISP Verizon FIOS, is probably blocking port 25? I have configured IPTables in my Linux server. Should I disable the IPtables and test it out. Can I configure Postfix to use another port, and forward the port on my ROUTER.

Any help is greatly appreciated.

SOLUTION -->

As it turns out, Verizon FIOS is blocking all OUTGOING email ports, Verizon is not allowing relaying at all. I was able to use GMAIL SMTP port 587server. I configured POSTFIX to use GMAIL as relay.

Few changes to configuration. Before, I could check my mail queue. All mails gone already. LOL :)

Check your FW rules, if they are good try to reach it via telnet:

telnet 66.196.118.37 25
Trying 66.196.118.37...
Connected to 66.196.118.37.
Escape character is '^]'.
220 mta1474.mail.bf1.yahoo.com ESMTP ready
quit
221 Bye

If you can't get a connection, complain at your ISP he probably blocks
port 25, get 50% back of your ISP charges and leave (you'd pay 100% for
half the internet capabilities).
