Hello,
Please ensure you run the mysql dump command exactly as shown within the knowledge base article and that you manually type the command into your CLI replacing the values in <> symbols with the correct password and drive of your system.
If you have more than one Symantec Mail Security for SMTP system, make sure you are running this command on the Symantec Mail Security for SMTP 5.0.X control center, not a scanner.
Windows:
<Drive>:\Program Files\Symantec\SMSSMTP\mysql\bin\mysqldump.exe" -ubrightmailuser -p<password> -h127.0.0.1 brightmail > smssmtp5.sql
Linux/Solaris:
/opt/Symantec/SMSSMTP/mysql/bin/mysqldump -ubrightmailuser -p<password> -h127.0.0.1 brightmail > smssmtp5.sql
If this does not work please post information on the following: a) the full output of the error message b) the input mysqldump command used c) Platform Symantec Mail Security for SMTP 5.0 is installed on.
Regards,
MJF
