[RCU] Password change with roundcube

Hello all!

A question about the password plugin. When I login to my email-account with roundcube, I connect to the service that runs on port 143 and ask there, if I may login, right? dovecot is running on port 143 and looks in his passwordfile and permits the login or does not, right?

For sending email, sasldb is used on MTA-side to permit sending or not.

So when I want to use the passwd-plugin with sasl, it only changes the passwd in the sasldb for sending email, the password in the passwordfile of dovecot is not changed and the user must login with the password once specified, right?

Is there a way, to let the users change their password themselves without requiering administrative intervention?

Kind regards

Andreas
