Send service email to all my users?

[Ted Fines]

Can you generate a list of your users?

Once you have that, a simple Perl program could be used to send them each a 
message, using the Perl Mail::Sender module.  Here's a snippet of a Perl 
program we use to send mass email:

Just get your list of users and put it into the '@list_of_all_userids' 
array and they'll all get mailed.

#!/bin/perl -w
use Mail::Sender;
my $c=0;
my $sleep_time=60;
my $emails_between_sleep=100;

foreach my $userid (@list_of_all_userids) {
    $c += 1;
    &mail_it($userid);
    if ($c > $emails_between_sleep) {
        # so the mail server doesn't get killed
        sleep $sleep_time;
        $c = 0;
    }
}
sub mail_it {
my ($to) = @_;
my $mailhost='your.smtp.server';
my $from = 'from_addr at domain.net';
my $subject = 'Some kind of subject';
my $body = 'This is the message body.';
my $file = '/path/to/attachment';

$sender = new Mail::Sender {
                            smtp => $mailhost,
                            from => $from
                           };
$sender->MailFile({
                   to => $to,
              subject => $subject,
                  msg => $body,
                 file => $file
                 });
}
