Having an issue with locally generated mail being deferred
It's either my mail server or the firewall in terms of a setting i have wrong or i missed. When the mailserver tries to send mail from email@example.com it goes to the right external ip 220.127.116.11 but the packets die. I have setup a packet filter rule to allow that traffic to no avail. I have port 25 form the outside forwarded to the box in question(it runs zimbra). When i try to telnet to mail.faithsbc.org port 25 it hooks in. When i try to telnet to 18.104.22.168 port 25 it times out. I've also setup hosts definition of 22.214.171.124 to mail.faithsbc.org to no avail on the mail server. I can ping it form the mail server but port 25 traffic won't make it. Maybe it won't due to the fact it's a loop. I may have to mod the mail server internally so root@ heads to it's internal address. FYI originating ip for the mail in question is the loopback address 127.0.0.1. I know it's got to be something simple..any ideas?
