Summary
IMSVA 9.0 Critical Patch Build 1503 is released and is now posted in Trend Micro's Download Center.
Details
This critical patch resolves the following issues:
- For IMSVA versions released before version 9.0, when the administrator configures the Administration > SMTP Routing > Message Deliverysettings and inputs a fully-qualified domain name (FQDN) for the target "Server Address", Postfix will try to query the MX record of the FQDN so that:
- if the MX record exists, IMSVA will deliver the mail to the MX record
- if the MX record does not exist, IMSVA will try to query the corresponding A record and deliver the mail to the A record.
- The IMSVA 9.0 GM build queries only the A record of the FQDN. This may cause email delivery issues when delivering messages between different IMSVA versions.
Critical Patch 1503 prevents delivery issues by implementing the following changes:
- If a user imports configuration files from versions older than version 9.0 GM build, IMSVA will keep the same behavior as the previous version.
- If a user adds a new delivery setting in IMSVA 9.0, the user has the option to configure IMSVA to query the MX record or A record.
Note: This solution will be added to the repacked version of IMSVA 9.0 GM build and in Hot Fix 1504 so that upgrading to any of these versions also resolves the issue.
