    Description

      This means if new mails are sent faster than this queue is handled it can crush the memory. That's what is happening on myxwiki.org for example where we get a OOM and a 350MB PrepareMailQueueManager when notifications mails kicks in.

      Ideally a BlockingQueue should be used with a limited (and probably configurable) size. That way when the queue is full whatever want to send a new mail wait a bit just the time for the queue to have room.
