ServersHere are the servers needed for EMAIL to work

    1. Web Mail

    • Provides browser-based email access for users who don’t use dedicated email clients.

    2. IMAP/POP Server

    • Handles incoming email and allows users to retrieve messages. IMAP supports multi-device sync; POP3 is simpler and downloads emails locally.

    3. MTA (Mail Transfer Agent)  server

    • Software like Postfix, Exim, or Sendmail that routes outbound and inbound emails between servers.

    4. MDA (Mail Transfer Agent)  server

    • Delivers email into users’ mailboxes, often paired with MTA systems.

    5. SMTP Relay server

    • An SMTP relay server securely forwards outgoing email messages from a sender's server to the recipient's email server across the internet.

    6. Antivirus Server

    • An antivirus server scans, detects, and removes malware from network-connected devices and email traffic to protect enterprise systems from cyber threats.

7. Authentication Server (LDAP / Active Directory)

  • Manages user identity and permissions, often connected to internal directory services.


8. Email Archive/Retention Server

  • Stores emails securely for legal, compliance, and business continuity reasons.

9. Spam Filtering / Anti-Spam Gateway

  • Detects and blocks spam messages using blacklists, heuristics, or AI-based algorithms.

10. Encryption or Public Key Infrastructure (PKI) Server

  • Manages digital certificates and email encryption for secure end-to-end communication.

11. Monitoring & Logging Server

  • Tracks system health, email traffic, errors, and suspicious behavior for audits and diagnostics.

12. Backup & Disaster Recovery Server

  • Performs regular backups and ensures recoverability of email data in case of failure or attack.
