The email accounts you create on our servers can be accessed using your email client of choice (Outlook, Thunderbird, Entourage, etc.) or through a Web mail interface, similar to how people typically access free, online email accounts, such as Yahoo, Hotmail and GMail.
Keep in mind, email can accumulate quickly within your hosting account. As a rule, it is a good idea to make sure you have at least 10mb of available space for every active email account if people are using an email client, and at least 50mb for people who use the available Web mail interface.
