Easy
Easy to use, easy to manage.
Users can connect with DBMail from Outlook, Eudora, Thunderbird or any other email or webmail client. Advanced access control capabilities enable power users to create shared folders and virtual folders (views).
DBMail's user management facilities implement low-privilege email user accounts. User management is performed centrally, eliminating the need to synchronize password entries.
Migrating users from POP to server-side IMAP email is a no-brainer that requires no server-side reconfiguration.
