Trend Micro InterScan Messaging Security Virtual Appliance Administrator’s Guide 9-18 • Rate (%): Type the maximum number of allowable email messages signalling bounced mail (the numerator). • Total mails: Type the total number of bounced email messages out of which the threshold percentage is calculated (the denominator). Consider the following example. Duration to monitor: 1 hour at a rate of 20 out of 100 During each one-hour period that blocking for bounced mail is active, IMSVA starts blocking IP addresses when more than 20% of the messages it receives are bounced messages and the total number of messages exceeds 100. Note: The LDAP service must be running to check bounced mail. 5. Next to Triggering action, select one of the following: • Block temporarily: Block email messages from the IP address and allow the upstream MTA to try again. • Block permanently: Never allow another email message from the IP address and do not allow the upstream MTA to try again. 6. Click Save. Step 5: Configuring Email Reputation Email reputation verifies IP addresses of incoming email messages using the Trend Micro Email Reputation database.
To configure Email Reputation: Configuring IP Filtering Settings 1. Choose IP Filtering > Email Reputation from the menu. The Email Reputation screen appears. 2. Select the Enable Email Reputation check box. 3. Click a radio button next to one of the following, depending on your level of service, and configure the settings: Standard: • Default intelligent action: Email reputation permanently denies connection (550) for RBL+ matches. • Take customized action for all matches: 9-19
