Release notes for Symantec Mail Security for SMTP 4.1.2 through 4.1.16 This page contains the public release notes for Symantec Mail Security for SMTP 4.1.2 through 4.1.16.
Symantec Mail Security for SMTP 4.1.16 build 48 Symptom: Incomplete quarantine entries cause interference with other submissions. Solution: Modified the check for incomplete quarantine entries prior to saving the data. Symptom: Heavy load may cause Solaris to make multiple attempts to delete a message. Solution: Limited number of message deletion attempts.
Note for Windows users with Symantec AntiVirus Corporate Edition: If you run Symantec AntiVirus Corporate Edition version 184.108.40.2060 or earlier, you may see spurious virus alerts as Symantec Mail Security for SMTP processes email. To resolve this problem, upgrade to Symantec AntiVirus Corporate Edition 10.1.5.5000-17 or later. You should only need to exclude the Symantec Mail Security for SMTP queues directory from scans by Symantec AntiVirus Corporate Edition.
Notes for Solaris users:
ln -s /opt/SMSSMTP/bin/jlu.jar /opt/Symantec/LiveUpdate/jlu.jar
Note for all users:
Symantec Mail Security for SMTP 4.1.15 build 47
Symptom: Symantec Mail Security for SMTP marks files from Symantec AntiVirus CE that are destined for the quarantine server as malformed.
Solution: Modified release notes text, adding a note for Windows users running Symantec AntiVirus Corporate Edition that recommends upgrading to version 10.1.5.5000-17 or later. No change was made to Symantec Mail Security for SMTP 4.1.
Symptom: A specific partial message was being handled incorrectly.
Solution: Corrected processing in the decomposer to correctly display the message partial error.
Symantec Mail Security for SMTP 4.1.14 build 46
Symptom: Provide a method to disable the update of Heuristic SPAM definitions.
Solution: Created a variable for the SMSSMTP.cfg file that inhibits LiveUpdate of Heuristic spam definitions when set to '1'. To disable the update add the value "HeuristicSpamDisableUpdates=1" to the SMSSMTP.cfg file and restart the service. To re-enable LiveUpdate for Heuristic spam definitions, completely remove the "HeuristicSpamDisableUpdates=1" value and restart the service.
Symptom: Particular Korean encoded email caused thread to stop processing.
Solution: Corrected processing code to add bytes to the end of a string when an encoded DBCS language is encountered that extends beyond the allocated buffer size.

Solution: Changed code to limit maximum extract time to 60 seconds and hold email instead of dropping when container limit disabled.
Symptom: SPAM file buffer overflow cause when JIS ending escape sequence missing
Solution: For Japanese encoded subjects, a check is made to verify the ending escape sequence is JIS. If the sequence is missing an attempt is made to convert the string by SHIFT JIS. Failure of conversion is logged to the original undecoded subject as ASCII.
Symantec Mail Security for SMTP 4.1.12 build 43
Symptom: Only the log in page is sent by HTTPS protocol when in secure mode
Solution: Log in page now correctly transmits by HTTPS when in secure mode. A security modes change requires the restart of the service. Flush the browser cache.

Message: When a change is made to security settings a message shows. The message is "Changing security settings requires the application be restarted."
Symptom: Program blocks email even when container limits disabled.
Solution: A Checkbox is added for container limits. If the no check is in the box, messages are delivered regardless of depth. No warning is displayed and deliveries can result in viral email delivery.

Symptom: Content filtering fails for specific characters
Solution: Upgraded CSAPI

Solution: Corrected checks, so email with scan errors is placed in the Hold queue.
Symptom: Program blocks email despite disabling container limits.
Solution: Added code to check the on or off check box for container limits. If the container limit box is not checked, email is delivered regardless of depth. No warning is displayed. This may result in potentially viral email being delivered.
User Interface: Added text recommending users do not disable container limits. Customers will need to uninstall product and reinstall the product to see the disclaimer on the web interface.

<installed directory>\csapi\BMI\etc\ directory
A scan error for every email will be placed in the log file when the Cert.pem is not downloaded correctly. Users should restart the service, allowing the Heuristic Anti-Spam engine to enable.
