This should be an easy one. I'm trying to get postfix going. I've never done this before. I followed the directions at http://wiki.centos.org/HowTos/postfix. I opened port 25:
iptables -I INPUT -p tcp -m tcp --dport 25 -j ACCEPT
Here's an attempt to send mail:
[motor@localhost motor]# mail -v larry.martell@gmail.com Subject: test test . EOT larry.martell@gmail.com... Connecting to [127.0.0.1] via relay... 220 localhost.localdomain ESMTP Postfix

But I don't receive the mail. In a file in /var/spool/postfix/defer I see:
larry.martell@gmail.com: connect to alt2.gmail-smtp-in.l.google.com[2607:f8b0:400d:c00::1a]:25: Network is unreachable recipient=larry.martell@gmail.com offset=654 dsn_orig_rcpt=rfc822;larry.martell@gmail.com status=4.4.1 action=delayed reason=connect to alt2.gmail-smtp-in.l.google.com[2607:f8b0:400d:c00::1a]:25: Network is unreachable
Have I missed a step or done something wrong?
most home broadband providers block outbound port 25 from reaching any smtp servers other than the ones that they provide and typically require authentication in order to stop spam.
This is not a home machine. It's my client's machine on a corporate network.
