Outbound Email Failing

I'm not having much luck getting vCAC to send out email notifications. I've added the mail server to the tenant, and have enabled notifications under my user prefs.

In the Catalina.out file I see the following:

2014-07-09 16:49:29,815 [queue-pool-executer-2] [notification] ERROR com.vmware.vcac.platform.service.integration.store.CafeJdbcChannelMessageStore.addMessageToGroup:45 - Exception during add message to queue: defaultMessageStore:errorChannel
