How can I let users open new accounts through IMP?
[IMP 2.2]: There is rudimentary account-signup functionality built into Horde 1.2 (IMP 2.2), which will allow users to fill out a form to request an account, and then send the collected data to a specified email address. To enable it, set the following in horde/config/horde.php3: $default->signup = true; $default->signup_email = ‘address which receives account requests’; There is currently no automated account creation facility in IMP. If you feel you are capable of writing this (meaning that you know how to write secure setuid programs!), look at horde/signup.php3. Keep in mind that allowing users to create accounts without any sort of admin authorization might not be a good thing. [IMP 3.x]: This functionality is not available in Horde 2.x or IMP 3.x at this time.
