Yeah, it does accept that if you comment out the one rule. Strange thing 
is, this file is copied from the original mailserver, running the same OS.

If you re-enable the one line below it gets this error:

Applying iptables firewall rules: iptables-restore: line 14 failed
                                                            [FAILED]
