According to this discussion, there's no global (SUL) limit on the number of emails sent daily; so in order to prevent spam, canvassing and other mass disruptive email sending, please set a reasonable global hourly limit on the number of emails and email receivers. A good-faith user will rarely need to send, for example, 100 emails or email 100 users per hour.
