Hi,
We use the following crude script to take all of the Majordomo alias and
vut files, and compile them into one file that sendmail uses. That way, we
don't have to update the sendmail configuration when we add a new domain
to Majordomo.
We run this once an hour. Obviously, it can be made to do other things as
well.
In addition, the attached program apparently does what you need it to do
-- so work that in with this, and you have your solution.

use File::Listing;
&init;
&delete_files;
&parse_domains; # This routine will create the vut + alias files as well
©_files;
&alivut;
sub init {
$mj2domains_dir = "/usr/local/mj2/lists"; # Where Mj2 stores the lists/domains
$tmp_dir = "/etc/mail/mj2";
$sendmail_dir = "/etc/mail"; # Where sendmail stores its files
$newaliases_exec = "/usr/sbin/newaliases"; # The location of the newaliases program
$makemap_exec = "/usr/sbin/makemap";# The location of makemap
$makemap_type = "btree";
$sendmail_vut = "virtusertable.mj"; # The location of the central vut file.
# It will be created under $sendmail_dir
$sendmail_aliases = "aliases.mj"; # The location of the central aliases file.
# It will be created under $sendmail_dir
### you shouldn't need to change anything below this line
$mj2files_dir = "$mj2domains_dir/ALIASES";
$alias_tmp = "$tmp_dir/mj-alias.new";
$vut_tmp = "$tmp_dir/mj-vut.new";
}

=head1 NAME
buildvirtuser - Build virtusertable support from a directory of files
=head1 SYNOPSIS
buildvirtuser [-f]
=head1 DESCRIPTION
buildvirtuser will build /etc/mail/virtusertable.db and /etc/mail/virthosts
based on the contents of the directory /etc/mail/virtusers/. That
directory should contain one file per virtual domain with the filename
matching the virtual domain name and the contents containing a list of
usernames on the left and the actual address for that username on the
right. An empty left column translates to the default for that domain.
Blank lines and lines beginning with '#' are ignored. Occurrences of
$DOMAIN in the file are replaced by the current domain being processed.
Occurrences of $LHS in the right hand side are replaced by the address on
the left hand side.
The -f option forces the database to be rebuilt regardless of whether
any file changes were detected.
=head1 CONFIGURATION
In order to function properly, sendmail must be configured to use these
files with:
FEATURE(`virtusertable')dnl
VIRTUSER_DOMAIN_FILE(`/etc/mail/virthosts')dnl
If a new domain is added (i.e., by adding a new file to
/etc/mail/virtusers/), the sendmail daemon must be restarted for the change
to take affect.
=head1 EXAMPLES
Here are some example files from the /etc/mail/virtusers/ directory:
=head2 /etc/mail/virtusers/bsdunix.org:
# Services
MAILER-DAEMON gshapiro+bounce.$DOMAIN@gshapiro.net
