How it works

ActiveServer acts as a bridge between IMAP, CardDAV and CalDAV protocols (which are exposed by your mail server and Aurora/WebMail Pro) and an ActiveSync-enabled mail client.

Technically, it's implemented on top of Z-Push sync engine extended with a number of additional backends, adjusted and fine-tuned for seamless operation.
