How to change the password for an email account

You can change the password for an email account by logging in to the webmail interface (http://mail.yourdomain.com).

Once you are logged in, go to Settings >My Settings > Account Settings > User to change the email password.

If you do not know the email account password you will have to log in to webmail using the "postmaster" account to change the password. See "How to create a new email users" for instructions on accessing webmail using the postmaster account.
