E-mail Module:Double Opt-in

Objective

Centricity requires a Double Opt In for a User account to be active.

When a User registers, create a database entry in the User table for their double opt-in status: confirm = 0. Make sure there are no duplicate User entries.
The module will then send out an opt-in e-mail using the Kohana module Swiftmaill
1. Create a unique URL string that, when clicked, will set double opt-in the User (confirm = 1)
  1. On click, check that confirm = 0. If confirm = 1, then display an error message: "You have already confirmed you e-mail. Please login."
  2. If confirm = 0, this URL will also log the User into Centricity
    1. Use the Login Module in our application to perform the login.
    2. Login->Models/Login_BO->login( username, password, portal_id )
2. If Opt-in is received, the User table will be update to show this is an Opt-in user, no more email ( confirm = 1 )
3. If Opt-in is not received, then schedule a cron/schedule job to send one e-mail per day asking the user to opt-in.
  1. If a User has not Opt-in for seven days, the account will be marked as in-active ( status = 0 ).
4. There will be another link which User can Opt-out
  1. If a User click on the opt-out, the account will be marked as in-active ( status = 0 )
