Andrew, 

First of all, thanks very much!  Between you and Jim Miller, I got the
encouragement and guidance I needed.  The proof's in the pudding: see my from
address?  

Second, you had me ROFL for 10 minutes, positively giddy.  I knew anyone
*could* poke into my DNS with nslookup, but that's the first time anyone *did*. 
It just felt very funny to have my homely set of names echoed back to me. 
Very thorough.  Thanks for that advice, too.  

Third, it looked to me like some of the messages I got from you were sent to
jklowden@lowden.schemamania.org.  I'm very confused about that.  I do use a
bimap command in ipnat for lowden, but I'm still surprised mail got through
because the external address isn't exposed in the DNS.  Care to comment?  

What I did between 7 and 9 tonight:  

I wound up following the directions in the readme (big surprise), adding your
contents to a copy of usr/share/sendmail/cf/netbsd-proto-IPv4only.mc.  

I m4'd it, trying (with doubts) to hup sendmail.  She stopped.  OK, so sendmail
is not bind.  

Then she wouldn't restart, complaining:

/etc/mail/sendmail.cf: line 84: fileclass: 
	cannot open '/etc/mail/local-host-names': 
		No such file or directory

So I did what anyone might try:

	echo lowden >/etc/mail/local-host-names
	
which was all I had to do before sendmail -bd.

The latter point is clear, but I don't know what you mean by "mx records for
lowden, ... that all point to home".  I re-read the mail chapter in "DNS and
BIND", which goes to great lengths to explain backup mail hosts, but I didn't
notice anything about MX records that "point to" anything.  What am I missing
here?  

Once again, thanks.  It was amusing and interesting.  I learned something.  
I'm very glad I asked for help instead of punting and switching to another MTA. 

Regards,
