No. Unlike competing services, who typically limit the size of your individual e-mail boxes on the server to a low number, such as 5 MB, LFC Hosting is unique by not placing a separate space quota on your e-mail accounts or a limit on the size of messages that you can send and receive. Rather, the disk space that your e-mail accounts occupy on our e-mails servers is limited only by the total disk space included with your account, allowing you send and receive large e-mail attachments and avoid worrying about your e-mail account exceeding its quota when you are on vacation.
