Apparently it isn't.

Err, the firewall built in to OSX doesn't seem to be iptables, and there
is no /etc/sysconfig directory. I believe the firewall is ipfw:

    $ locate ipfw
    /private/var/log/ipfw.log
    /private/var/log/ipfw.log.0.gz
    /sbin/ipfw
    /usr/share/man/man8/ipfw.8

Unfortunately, that log file isn't currently set up to log anything:

    $ ls -l /var/log/ipfw.log
    -rw-r-----    1 root     admin      0 Oct 25 04:43 /var/log/ipfw.log

But like I said earlier, going into Apple's GUI and turning off the
firewall doesn't seem to change the observed behavior -- the telnet to
port 25 still fails immediately, whether or not the firewall is on or not. 


Hmm....
