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
<samle send elided>
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?
Unreachable... maybe you should have OUTPUT open, also?
