One of the Linux server running with Plesk v 10.2.0 has to be:
1. tweaked for security leak
2. Automated emails are generated and every second there are 100s of email in mail queue, it should be fixed.
3. Over all server should be tweaked and should make the server perform well.
4. Scheduled backup should be set...
5. May stick with you for years together, if you do a good job.
