Mail Server Management

Server Management Services

A mail server is only as reliable as the infrastructure it runs on. I provide end-to-end Linux server management focused on maintaining high availability, security, and performance for email systems.

What I Manage

• Linux server provisioning and hardening (Ubuntu, CentOS, RHEL)
• Mail Transfer Agent (MTA) management — Postfix, Exim
• cPanel and CWP (CentOS Web Panel) administration
• RAID monitoring, disk health checks, and storage expansion
• Automated backup configuration and offsite replication
• DNS zone management — A, MX, PTR, SPF, DKIM, DMARC records
• Firewall configuration — iptables, firewalld, CSF
• SSH hardening and access control (key-based auth, fail2ban)
• SSL/TLS certificate management and HTTPS enforcement
• Server performance monitoring (load, memory, disk I/O)
• Log analysis and proactive issue detection
• Kernel updates and security patch management

Monitoring & Uptime

I set up comprehensive monitoring including service health checks, mail queue monitoring, disk space alerts, and automated recovery scripts to maintain 99.9% uptime for critical email infrastructure.

Security Hardening

• Regular security audits and vulnerability scanning
• Intrusion detection and prevention setup
• Rootkit scanning with rkhunter and chkrootkit
• Automated security updates and patch management
• Access control lists and permission hardening
