You will have access to our webmail system so you can access your email from anywhere in the world with a web connection.
Just type in your url with a /webmail, add in your password and username and you have access to your emails.
Remember though that if your emails are being downloaded by sombody else, like your PA, they will no longer be on the server.
To remedy this you can do one of two things:
1) Via your Email Client, like MSOutlook, set it that your emails will stay on the server for a specified time then be deleted or just leave them on the server until you delete them via your web mail.
2) Create a forwarder via your cPanel, when an email is forwarded it leaves the original on the server.
