OX Dovecot Pro provides different security options throughout the product. A secure software architecture minimizes the chance and impact of any security issues. Emails are stored securely and can be sent fully encrypted and archived, while frontend security is provided by OX Abuse Shield.

OX App Suite and OX Dovecot Pro


Both OX Dovecot Pro and OX App Suite are strong on their own, but even better together. Various innovative OX App Suite features and functions are based on OX Dovecot Pro, like push notifications, unique advertising options, automatically tabbed inbox, global attachment view and virtual folders (patent US9628428). It is for this same reason that Open-Xchange used both OX App Suite and OX Dovecot Pro in their OX Cloud solution.
