I just went to my webmail, and it says I'm 93% full, and that my quota is 250MB. It's supposed to be 1GB.
Where did you get that idea? My web mail is 250 MB - always has been.
Have you cleaned up your mailboxes on your webmail account? Emptied your trash, etc? If you use a real e-mail client - Outlook Express, Outlook, Eudora, etc.- you could download your e-mails from the server and not have to worry about any quotas.
