title: Best way to send 10,000+ emails with PEAR/Mail_Queue
body: <p>I have a cron which generates the whole mail info and puts in a database table using <code>$mail_queue-&gt;put(.....)</code> with an option to delete emails after they're sent.</p>
  
  <p>Here's where I need a little help: What is the best way to send the emails after I have the above info? Running the <code>$mail_queue-&gt;sendMailsInQueue()</code> right away, using other cron job(s) or something else?</p>
  
  <p>The server limit by the way is 100 emails / minute. Currently the last csv diff for <code>Mail_Queue</code> is not applied (currently working with the support on that), so I can't use the "delay" option.</p>
  
  <p>I had an idea to use the <code>$seconds_to_send</code> option, but it's calculated on the base of create_time field, which isn't a big help, but it's also an option.</p>
  
  <p>Any ideas and suggestions would be really appreciated.</p>
