Mail transfer agent MTA Postfix Transport Layer Security(TLS) Secure Mail server & SMTP-AUTH
IntroductionPostfix 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
MethodologyLinux-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 Testing
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 ...7. perform backups new cloud-based email service6. start using cloud based-email solution5. Assign the registered domains to several DNS records Cloud-4. forward email from old server to new cloud mailbox Based Email Service3. create a profile to remember all email accounts2. setup new users, storage, aliases, and SharePoint1. new host can import emails from the current one
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.
