scalability and performance to suit your business needs

Performance & scalability

Our architecture supports installation on a single server or configured into ‘shards’. Shards are separate, isolated instances tuned to support a certain number of users. Shards can be stand-alone, replicated in the same facility or even have geo-redundant back-up.

atmail provides a robust solution running on the latest enterprise level LAMP stack. You can install as a full stack, turnkey solution or on-top of your existing infrastructure (webmail-only solution).

Featured plugins

A key strength of our webmail is its flexibility and extendibility. The atmail plugin framework allows you to easily extend the platform to meet your needs or customise your user’s experience without editing any core atmail code; ensuring that it is easy to keep your system up-to-date!
