CassandraMessageDAO always throws "Mailbox is over quota" when quota is set to 0

[johnwiesel]

The config states: "To disable quota parameter set it to 0."

But setting it to 0 does not work as expected. Put requests always return "Mailbox is over quota" message.

Suspected reason in CassandraMessageDAO.java:144

        if ((requiredBytes > Configurator.getDefaultQuotaBytes()) ||
(requiredCount > Configurator.getDefaultQuotaCount()))
{
logger.info("Mailbox is over quota: {} size={}/{}, count={}/{}",
