It's not totally clear.  I suppose it's a somewhat unusual situation 
because I'm only using my computer and not an intranet or anything along 
those lines.  This configuration is down to postfix?

I don't think I'm using a virtual domain but only a local domain.  (And 
only a local domain, nothing should go out to the internet.)

I'm going with using my vanity domain:

root at dur:~#
root at dur:~# newlist mailman
Enter the email of the person running the list: thufir at dur.bounceme.net
Initial mailman password:
To finish creating your mailing list, you must edit your /etc/aliases (or
equivalent) file by adding the following lines, and possibly running the
`newaliases' program:


dur.bounceme.net is a local domain.  It doesn't exist in any DNS I'm
aware of.  It's just a FQDN which I got from no-ip.com as a free "host". 
  It's unique, but I don't own the bounceme.net domain as a whole, only 
have access to that sub-domain.

I have postfix configured, hopefully, to only send mail to this machine
and not to try to send anything to the internet.

I'm not on the wrong track with mailman?  Assuming Postfix and my hosts 
and so forth are configured correctly, of course...
