Trend Micro InterScan Messaging Security Virtual Appliance Administrator’s Guide 10-10 3. Specify the Message Limits settings: • Maximum message size: Type the number of megabytes. • Maximum number of recipients: Type the number of recipients from 1 to 99999. 4. Specify the Relay Control parameters to have IMSVA reject messages matching the selected condition. 5. Specify the Relay Domains. IMSVA relays the messages to the listed domains. Tip: When importing, import both the exact domain and all sub-domains for best results. The following shows sample content of a domain list text file: • domain.com: Imports the exact domain • *.domain.com: Imports all sub-domains • domain.org: Imports the exact domain Note: The import file must be a text file containing one domain per line. You can use wildcards when specifying the domain. 6. Specify the Permitted Senders of Relayed Mail. 7. Click Save. Tip: For security reasons, Trend Micro recommends that you avoid open relay when configuring the message rule settings. For more information on how to avoid open relay, refer to the Online Help and the FAQ section in this manual.
About Domain-Based Delivery Scanning SMTP Messages IMSVA maintains a routing table based on the domain names of recipient email addresses. IMSVA then uses this routing table to route emails (with matching recipient email addresses) to specified SMTP servers using domain-based delivery. Messages destined to all other domains will be routed based on the records in the Domain Name Server (DNS). Relay Domains and Domain-Based Delivery The domains you configure for relay domain settings (for SMTP Message Rules) are different from the domains you configure for domain-based delivery settings (for Domain-Based Delivery). Relay domains: IMSVA relays email messages that are sent only to the relay domains. For example, if the relay domains list includes only one domain, "domain.com", IMSVA will relay only email messages that are sent to "domain.com". Domain-based delivery domains: IMSVA delivers email based on domain-based delivery. For example, if the delivery domains include "domain.com" and the associated SMTP server 10.10.10.10 on port 25, all email messages sent to "domain.com" will be delivered to the SMTP server 10.10.10.10 using port 25. Configuring Domain-based Delivery Settings Specify settings for the next stage of delivery. IMSVA checks the recipient mail domain and sends the mail to the next SMTP host for the matched domain. When importing a Domain-based Delivery list, the list must be in a valid XML file. Each entry consists of the following: [domain name],[server name or IP address]:[port number] For example, all of the following are valid entries: • domain1.com,192.168.1.1:2000 • domain2.net,192.168.2.2:1029 • domain3.com,smtp.domain3.com:25 • domain4.com,mail.domain4.com:2000 10-11
