Yes, in addition to using a desktop mail program such as Outlook, Outlook Express, AppleMail, Eudora, etc. you can access your mail using webmail. Webmail is most commonly used when you are travelling or away from your primary computer.
To login to your webmail account, if your mail account is hosted on one of our Windows servers go to http://webmail.earthplaza.com If your mail account is hosted on one of our Linux servers, go to http://yourdomain.com/webmail From there you can login to either HORDE, ROUND CUBE or SQUIRRELMAIL. All are very similar and easy to use.
Regardless of which webmail program you use, be sure to login with YOUR FULL EMAIL ADDRESS as your user name and your mailbox password.
