I was not sure where to send the question so when in doubt try this
list.
FreeBSD FW 4.6-RC FreeBSD 4.6-RC #0: Mon May 27 23:46:22 CDT 2002
root@FW.rhbsd.dhs.org:/usr/obj/usr/src/sys/FW i386
To make a log story short the above machine is my DNS, DHCP server, and
Firewall running NATD.
Using ipfw and the rules that Dan O'Connor, from Freebsd cheat sheets,
suggests on Setting-up a Dual-Homed Host.
The problem: Sendmail stopped working about 5 days ago. Let me rephrase
that, mail delivery stopped about 5 days ago.
inside interface ip: 192.168.4.1
if {
telnet 192.168.4.1 25
}
Trying 192.168.4.1...
Connected to ns1.rhbsd.dhs.org.
Escape character is '^]'.

if {
telnet localhost 25
}
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Operation timed out
telnet: Unable to connect to remote host
funny thing is that telnet localhost 25 only looks as above if I remove
the following from my rules set:
${fwcmd} add 200 deny all from any to 127.0.0.0/8
else {
telnet localhost 25
}
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Permission denied
telnet: Unable to connect to remote host
I can also do {
telnet 0 25
}
Trying 0.0.0.0...
Connected to 0.

May 30 07:53:51 FW sm-mta[5052]: g4UCrRuX005052: ns1.rhbsd.dhs.org
[192.168.4.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA
I checked:
/etc/resolv.conf
/etc/hosts
/etc/hosts.allow
I tried just telling sendmail to deliver mail somewhere else like
192.168.4.1 where I was able to telnet to port 25 but seems like I am to
dense to do it.
# cd /etc/mail/
# make all
modified fw.mc (which was created after make all)
by adding LOCAL_RELAY and since it did not work MAIL_HUB
I also explicitly allow localhost and 127.0.0.1 on
/etc/mail/access
Which make updated the access.db file.
# make cf
# make install
# make restart
Finally, it follows some of the errors on my maillog file.
# tail -f /var/log/maillog

After many days of reading and trying different things I don't know
where else to look some advice will be greatly appreciated.
