As outlined in the Acceptable Use Policy, e-mail accounts may not be used to send unsolicited bulk e-mail, nor spam of any kind. Additionally, forging or attempt to make e-mails appear to be from someone else, will also result in termination of the e-mail account.
Mailboxes may be up to 10 MBs in size. Additional space is available for a fee.
Outgoing e-mail messages, and their attachments, also may not exceed 10 MBs.
