Description
Happycoders otp-wrapper is a multi-threaded IMAP wrapper that replaces LOGIN authenticate method by an OTP one.
This wrapper keep a persistent connection with the IMAP server during a few minutes after the last action (given in the configuration file).
This wrapper allow you to use you favorite webmail (squirrelmail, IMP, ...) with a OTP authentication. We have also implemented a new IMAP command (OTP-LOGOUT) to force wrapper to close the persistent IMAP server connection.
We have created a small patch for squirrelmail 1.4.3 to send (OTP-LOGOUT) command when you signout.
This software is released under the term of the GNU GPL licence.
