Introduction
Postfix security Transport Layer Security (TLS) : make privacy by using symmetric
cryptography and a keyed message authentication code message reliability.
SMTP-AUTH : which use Simple Authentication and Security Layer (SASL) Internet Standard method which can be used with protocols such as SMTP for adding authentication support to connection-based protocols .
Main aim of using postfix significant impact on Internet mail performance and security
Methodology
Linux-based platform has been configured as a server with postfix and covers TLS and SMTP_AUTH.
Implementation Steps: Installation (postfix) Configuration Authentication (SMTP_AUTH)
Digital Certificates Encryption

Migrating to cloud environment
• Cloud-Based Email Services:– cheaper than running personal email service on-premise.– rapidly provision new users. More scalable.– Always run the latest software and configurations without upgrade
hassles.– Shift the financial burden from upfront capital expense to ongoing
operating expense.
Migrating to cloud environment cont ...
1. new host can import emails from the current one
2. setup new users, storage, aliases, and SharePoint
3. create a profile to remember all email accounts
4. forward email from old server to new cloud mailbox
5. Assign the registered domains to several DNS records
6. start using cloud based-email solution
7. perform backups new cloud-based email service
Cloud-Based Email
Service
Conclusion
• A mail server has been configured and tested in Linux environment using postfix Email Transfer Agent to “send, receive, and deliver” emails.
• The main aim what is ensuring a security level has also been achieved using TLS Security Certificates. Also authentication mechanism is supported using SMTP-AUTH.
• This implementation can be migrated to cloud-based level, over 7 phases to ensure end-to-end functions adaption.
• A further digging for enhancement might be applied in the mail transfer agent part. As well as the concept of heterogeneity.
