Look at the properties of the GWIA ---> SMTP/MIME --->Security Settings

Our Barracuda spam filter is showing the message 'server refused mail service' on a number of deferred emails. The emails are from a system that sends absence reports to school secretaries and principals, and we get over a hundred all at once. We have set the Barracuda to not rate limit this sender, but I'm wondering if there is a similar setting on the GWIA. The deferred emails are eventually delivered, but the schools want to get the emails right away, not 30 - 60 minutes later.

Is there a setting on the GWIA that limits incoming mail from a specific sender? Any other thoughts on why those emails would be refused/deferred?\
