Knowledge in managing and configuring access levels in Zimbra is a must. **Ideal Skills and Experience:** - Proven track record of successful Zimbra migrations - Strong understanding of email server security best practices - Experience in configuring automated backup and recovery for Zimbra - Familiarity with performance tuning for large-scale email systems - Excellent problem-solving skills and attention to detail This project is crucial for maintaining the integrity and reliability of our email communication.
