HOW WE DO IT

Technology

Postfix is just another open source software which is usually used for normal mailing purpose. But at HVM we had identified the advanced features of postfix and make it work like almost similar to enterprise mailing solutions. We also has developed custom scripts and methods to achieve this goal.

Postfix

  • Attaching IPs to the server (no: of IPs depend upon the sending limit)
  • Implementing and configuring multiple instances(or MTAs)
  • Assigning domains to each instance(or MTA)
  • Configuring DNS and rDNS for the domains
  • Configuring email authentication mechanism:
    • Sender ID/SPF configuration
    • DKIM configuration
  • We will implement a rotator instance, which will ease the task of pushing emails to multiple instances(or MTAs) without logging in to all those instances individually.
  • Implementing a separate instance for bounce handling
