We have Smartermail Abuse Detection set as follows:
Denial of Service SMTP: 100 connections in 10 minutes Block 60 minutes
Bad SMTP Sessions (Harvesting): 30 connections in 60 minutes Block 60 minutes
Our SmarterMail Incoming Gateway is repeatedly being blocked by our primary SmarterMail Server lately. We are running our Incoming Gateway in SmartMail Gateway Mode.
Our Incoming Gateway is doing all Spam Checks on inbound email before handing it to our primary SmarterMail Server to deliver.
Is there a setting I should set to prevent it from being blocked by Abuse Detection rules? I assume that Whitelisting would defeat the purpose of the Gateway doing Anti-Spam checks if we did Whitelist it.
Weirder thing is I don't believe that it was ever getting blocked prior to upgrading to v14. Now it is happening almost every hour during peak hours (8am-4pm).
