What Happens When IMAP Server Is Installed On My VPS?

When IMAP Server is installed on your VPS, all of the existing e-mail users will be converted to IMAP automatically, and all newly created e-mail users will be set to IMAP.

What Happens When IMAP Server Is Uninstalled From My VPS?

When IMAP Server is uninstalled from your VPS, all of the existing e-mail users will be converted back to POP3 automatically, and all newly created e-mail users will be set to POP3. The location of your e-mail storage will be changed back to the default POP3 location on your account. Any user created folders (and their contents) will be lost, only the main Inbox data will transfer back to your POP3 storage location.
