Overview

An external client was experiencing issues with their Postfix mail server. The service was difficult to access at certain times, causing emails to become stuck in queues. They reached out for assistance to resolve the issue or to find a more reliable solution for their email needs.

Pros

  • Postfix is a reliable and affordable email service
  • Product is well documented
  • Postfix can work in cluster mode
  • Service is light on hardware

Needs

The client wants to rely on this service so emails can go through and alert teams on time. The service must be available or alert people in case of failure.

Cons

  • Client is not Linux friendly
  • Emails must be sent at critical time
  • OpenSource needs attention

Results

  • Logs and Configuration extract. Configuration optimisation w/ best practices
  • Server and service added to a monitoring solution
  • Offer to duplicate the server to ensure reliable distribution system
