We currently have 8 virtual domains tied to the same IP number. 3 of 
these (currently) have mailing lists attached under them. Two sets of 
lists are working (the simple ones).  The digested lists are not yet 
but I think that was a typo... I'll get back to it tonight.

This is not anything I've seen but then ours are working so I'll just 
press on with what we do and not try to address the problem directly.

I hope this helps.

First, we have the latest version of sendmail (8.9.2.1 (Berkeley)). 
Your mileage may vary if you have something older or are not using 
sendmail.

Second, we have a /etc/mail/virtusertable file. This requires enabling
    FEATURE(virtusertable)
in the sendmail.mc file as explained in the sendmail/cf/README file 
(see bottom of note); the sendmail.mc file is converted to the 
sendmail.cf file (you can edit the cf file directly but I wouldn't 
want to try ;-)

The virtusertable must be built with
        makemap hash virtusertable < virtusertable
to create a form that sendmail likes

Our table contains things like

info@macperl.org                                macperl-%1
webmaster@macperl.org                           macperl-%1
listmaster@macperl.org                          macperl-%1
macperl-forum@macperl.org                       %1
macperl@macperl.org                             %1


Third, (not required but helpful) we have done as suggested in the 
Majordomo INSTALL file and defined a separate aliases file for 
majordomo aliases

   define(`ALIAS_FILE',`/etc/aliases,/etc/aliases.maj')

in the .mc file. You know it works when newaliases builds both the
regular aliases and aliases.maj files.


Pressing on.

Under the main majordomo directory (/uer/local/etc/majordomo for us), 
I made subdirectories for each virtual domain.  Then I copied 
everything - Log file, executables, all the stuff that's usually 
under the majordomo directory, into each of those subdirs and set 
owner, group, and permissions appropriately.

Then I edited the majordomo.cf files for each virtual host/domain to 
be appropriate for that domain.

Then I went back to the majordomo src directory and rebuilt and 
reinstalled wrapper _for each domain_. Specifically I made a copy of 
the Makefile for each virtual domain and edited the W_HOME variable 
accordingly, as
 Makefile.sfpm
   W_HOME = /usr/local/etc/majordomo/sfpm

I now have
  /usr/local/etc/majordomo
  /usr/local/etc/majordomo/sfpm
  /usr/local/etc/majordomo/sfpm/lists
  /usr/local/etc/majordomo/sfpm/wrapper
  /usr/local/etc/majordomo/sfpm/resend
  /usr/local/etc/majordomo/sfpm/...

Then I set up the lines in the aliases file:

  owner-sfpug:    me@sf.pm.org
  sfpug-owner:    owner-sfpug

  sfpug: "|/ulem/sfpm/wrapper resend -h sf.pm.org -l sfpug sfpug-list
  sfpug-list:  :include:/ulem/sfpm/lists/sfpug
  sfpug-request: "|/ulem/sfpm/wrapper majordomo -l sfpug"


The virtual user table handles what happens when requests come to an 
address at one of the virtual domains; whether it is send through to 
the "primary" domain or not, and how the address is modified _before_ 
it reaches the aliases file.

This is important! Otherwise you can get a  lot of User unknown errors.

Mail goes in to sfpug-request@sf.pm.org; mail is handled correctly; 
list mail goes out fro owner-sfpug@sf.pm.org.

Let me know if any of this doesn't make any sense or doesn't help (or 
does help).

========

virtusertable   A domain-specific form of aliasing, allowing multiple
                virtual domains to be hosted on one machine.  For example,
                if the virtuser table contained:

                        info@foo.com    foo-info
                        info@bar.com    bar-info
                        @baz.org        jane@elsewhere.net

                then mail addressed to info@foo.com will be sent to the
                address foo-info, mail addressed to info@bar.com will be
                delivered to bar-info, and mail addressed to anyone at
                baz.org will be sent to jane@elsewhere.net.  The username
                from the original address is passed as %1 allowing:

                        @foo.org        %1@elsewhere.com

                meaning someone@foo.org will be sent to someone@elsewhere.com.

                All the host names on the left hand side (foo.com, bar.com,
                and baz.org) must be in $=w.  The default map definition is:
