How to register additional webmail services in Plesk?
You can install on the server a number of webmail software packages and select which of them should be available to your users. Alternately, you can redirect your users to an external webmail service. To do this, register an external webmail service address with the Panel by adding a corresponding record.
All installed webmail packages and registered external webmail services are listed in the mail settings of hosting plans and subscriptions (on the Mail tab). There you can select which webmail to provision to users.
By default, Horde and RoundCube webmails are installed on Plesk for Linux, and only Horde is installed on Plesk for Windows. Additionally, Plesk for Linux supports Atmail, and Plesk for Windows supports the following webmail clients:
MailEnable Web Client SmarterMail Web Client IceWarp (Merak) Mail Server Web Client Atmail Open
