Hand in hand to a high-availability mail cluster

It doesn't always have to be the full-blown solution. We can implement smaller projects too, rapidly, in line with your needs and without compromising on quality. An example is e-pixler: we implemented a high-performance mail server cluster for this Berlin-based Internet agency in just two weeks.


The goal

Our task was to design, set up and deploy a fully functional and failure-resistant mail server cluster for the customer. The challenge lay in the tight deadline of only two weeks, and in providing full project management so as to free up the e-pixler team for their own jobs and projects.

The solution

We began with a workshop in which the requirements were defined. The results were reflected in the mail server cluster’s concept and design. Once this had successfully been set up we began the testing and documentation phase, before handing over the finished solution to deadline. We used the Hetzner Cloud as our data centre, which included other technologies:

  • HAProxy
  • ProxySQL
  • MySQL – Galera Cluster
  • Postfix
  • Dovecot
  • Apache 2
  • RoundCube

All components and services are of redundant design.

The result

We implemented the project from the initial concept through to documentation and put the mail server cluster into operation to deadline and to the customer’s complete satisfaction. Our competent project management freed up internal resources for other value-adding tasks.
