You can use either:
or
webmail.yourdomain.co.nz
You need to replace 'yourdomain.co.nz' with your domain name. Your password is the email password that would have been provided when your email account was set up. We don't keep records of email passwords, but we can reset them if required.
Note, that this will only work when you are using Web Drive's servers and that the webmail DNS is set up to go to their webmail server. If in doubt, just ask us.
