I have a subroutine that returns an array reference containing a list of users that I want to send mail to but always from the first user in the list.

The problem is, I think, that MIME::Lite cannot extract the users from the memory address?
"Cannot extract <mem. address here> from ARRAY<mem. address here>"

Any ideas??

sub get_users_array {
    my ($href, $index) = @_;
    my @all_users;
    
    my @sg_keys = keys %$href;
    
    foreach my $key (@sg_keys) {
        my $rec = $href->{$key};
        
        foreach my $mailbox ( sort keys %{ $rec->[$index] } ) {
            my $users_ref = $href->{$key}[$index]{$mailbox};
            push @all_users, $users_ref;
        }
    }
    
    return \@all_users;
}


$users_ref = get_users_array(\%sg_hash, $mbx_index);
                    
foreach my $user ( @{$users_ref} ) {
my $to = $user."@".$domain;
    my $from = $user->[0]."@".$domain;
                        
    if ($::Debug) { print "INFO: Sending email to $to\n" }
                        
    my $msg = MIME::Lite->new(
                    From => $from,
                    To => $to,
                    Subject => $subject,
                    Type => 'multipart/mixed'
                    );
