8/30    Thanks to the allknowing motd re:namebased virtual hosting.
        Next question (: i can no longer telnet to port 25 on my linux
        (and thus mail to/from any other machine no longer works) I
        can still send between accounts on the same machine, but that
        is all.  The only think i can think might have caused it is the
        additon of ipfwadm -F -p masq (for netword address translation).
        Any ideas?
        \_ that just looks bad.  there must be a -S 192.168.1.0/24 in there
           somewhere.  i don't know what security risks there are in that.
           can you telnet into any other service you're running?  maybe
           you just don't have sendmail running. "/etc/rc.d/init.d/sendmail
           status" or "psu -axu | grep sendmail". i would strongly
           discourage running any mta however since they are security
           hazards to begin with.  if you do you should run qmail instead.
                \_ run qmail only if you don't mind not being able use
                   .forward files and basically every other thing you're
                   used to using with mail.
        \_ If you can telnet port 25 on 'localhost' but not from outside
           its a firewall rule problem. If you can't even hit it from localhost
           are you not running a  'sendmail -bd' ?
        \_ Yeah.  Idea: do your own testing before wasting motd time.  Like gee
           did you try turning off NAT and then seeing if telnet works?

        users not volunteering their time and effort to help. Obviously,

        It is difficult to configure and its debugging facility totally

        mention its sucky security. Fuck sendmail, use postfix instead.

8/4     In sendmail on Linux, how do I write a rule which will quietly discard
        e-mail sent to nonexistent users? Default behavior is to bounce
        the mail back, but in the case of SPAM the From: address doesn't
        exist. I'd rather just toss such mail.

        how the implementation of tunneling detection works, and whether
        there are widely available implementations? We run a bunch of MS
