What mail server are you using?
passwd username
then all you need to do is run this command:Code: [Select]passwd username
I'm using dovecot on RHEL5, with Roundcube on a remote server. I use the normal password plugin. But the key is that you need to have something else on the IMAP server to do the actual changing. In my case I have poppassd on the mail server, which the plugin can talk to.
IMAP isn't involved. poppassd uses port 106, IIRC. All the plugin does is provide a web frontend to contact poppassd. Read the poppassd man page.
