Allow an unlimited number of emails to be sent with out giving administer print privileges

I'm probably not a common use case, however I've found your module helpful for my purposes. Users have to submit a report using our website, however they also need to be able to email a copy this report to people who are not in our system. The list of recipients can be upwards of 50 per submission and they've been known to submit the report several times in the same hour.

I didn't want to give all the submitter's administer print privileges so rather than just taking out the check completely I added an unlimited option to the hourly threshold drop down in mail_print.admin.inc (Line 137).

$form['settings']['print_mail_hourly_threshold'] = array(
    ....
    '#options' => drupal_map_assoc(array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50)),

$form['settings']['print_mail_hourly_threshold'] = array(
    ....
    '#options' => drupal_map_assoc(array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 30, 40, 50,'Unlimited')),

And added an additional check to print_mail_form_validate in print_mail.inc (Line 238)

$print_mail_hourly_threshold = variable_get('print_mail_hourly_threshold', PRINT_MAIL_HOURLY_THRESHOLD);

  if ((!user_access('administer print')) && (!flood_is_allowed('print_mail', $print_mail_hourly_threshold - count($to_array) + 1))) {

$print_mail_hourly_threshold = variable_get('print_mail_hourly_threshold', PRINT_MAIL_HOURLY_THRESHOLD);

  if (((!user_access('administer print')) && (!flood_is_allowed('print_mail', $print_mail_hourly_threshold - count($to_array) + 1))) || ((!user_access('administer print') && $print_mail_hourly_threshold == 'Unlimited')) {

I don't know if it is something that you want to add into the main module, but I thought I'd share.
