A message, with unusually long Message-ID: header, destined for quarantine gets stuck in the delivery queue with "Error: 421 Closing Connection". The sender eventually gets the bounce with code "554 5.4.7 [internal] exceeded max time without delivery" once the message gets removed from the delivery queue after Sent message time-out period has elapsed. Each delivery attempt to Quarantine results in "Data truncation: Data too long for column 'msg_id' at row 1" error logged in BrightmailLog.log.
BrightmailLog.log shows the following errors:
ERROR - Cannot create a spam message in the database.
com.brightmail.dl.DataAccessException: An unexpected database error has occurred. Please contact your system administrator. ; nested exception is:
com.mysql.jdbc.MysqlDataTruncation: Data truncation: Data too long for column 'msg_id' at row 1
ERROR - can't publish spam message
com.brightmail.common.BrightmailException: Cannot create a spam message in the database.
This issue has been addressed in Symantec Messaging Gateway (SMG) 9.5.3. Please update to the latest SMG release at your earliest convenience.
Workaround for earlier releases: change the action for Spam policy to Delete the message.
