Email throttling

Many email providers like Gmail, yahoo, and Hotmail all will limit the amount of email sent to their servers from a specific source by various means.  These include "only so many per hour" which is a type of throttling functionality.  For instance, if Gmail detects a mail server sending emails to it in a burst, it may limit or shut down the ability for that mail server to send additional email to it for awhile.
