Actually, it's in the sendmail configuration. In their default .mc file,
sendmail is configured like this:
dnl This changes sendmail to only listen on the loopback device 127.0.0.1
dnl and not on any other network devices. Comment this out if you want
dnl to accept email over the network.
DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')
Comment this out or delete it and you will be fine.

That's because it is a new kernel, 2.4, which comes with iptables by default.
It only has ipchains if you load it.
Theoretically you're supposed to rewrite all of your firewall scripts to use
iptables and not ipchains.

Yeah, I noticed this, I never really figured out what dcopserver does,
or why, but I get a lot more core dumps on 7.1 than I ever did on 6.2.
e.g. Netscape dumps core a lot more often.
Some other things that appear to be busted are somewhere between the
opendlap 2.0.7 server and the nss_ldap module. I had to get back the
nss_ldap-122 src RPM and recompile that to get things going, and even
now I find that my LDAP searches block for long periods of time or
fail occasionally.
