[lug] port 25 still blocked

[MATSUI Nobuki]

I tried flushing iptables rules before letting narc generating its own
rules.  Then, it's still blocked.  I tried using xinetd, setting up
/etc/hosts.allow and /etc/xinetd.d/sendmail, this did not work either.
Funny things is neighboring ports are opened (24 and 26.)  I wonder if one
needs to specify ports to be opened while installation time, otherwise
later reconfiguration would not work?
