I've had an email from a public member which has problems with the way LockMail application handles data quoting that it uses "plain text files". Plain text files are NOT used data is sent via a SSL connection to an PHP IMAP connection to then return emails to the client.

Your data is passed though a secure layer when access the server. You can read information about my activation platform which also uses the same method for returning and accessing data which was posted a while back. You can go to the link below.

By confirmed and registering to LockMail you must confirm that you have read this statement before using the application. A link is visible on the Cydia Repo which you can see before confirming to Install this application.
