Central E-mail System Quotas



There are limits to the amount of e-mail each individual may store on this shared system. Establishing these limits is necessary so that the central e-mail system is available to all.

The standard limit on the amount of e-mail faculty and staff can store on the central system (quota) is 30 mb. The limit on the amount of e-mail students can store on the central system (quota) is 15 mb. To put this in perspective, the size of the average e-mail message sent through the central system is 20kb. This means that if all messages are of average size, a faculty or staff member can store approximately 1500 messages and a student can store approximately 750 messages on the central e-mail system. (Note that messages with attachments are usually larger than the average size).

When an individual has used 80% of their space limit, an e-mail message is sent advising them that they are near the limit.

Notes:

  • One message with a large attachment could take a somebody from below 80% of their quota to 100% of their quota, so the message from the system may arrive after more than 80% of quota is reached.
  • When an individual's e-mail volume is higher than their quota, e-mail sent to them is bounced back to the sender with a message that the recipient is over quota.
  • An individual near their quota may receive several small messages that fit within their quota, but have a larger message (that would cause the amount of e-mail they are storing to exceed 100% of their quota) bounce.
  • The quota includes the e-mail in all folders within the webmail client. If e-mail has been deleted from the "Inbox", it still counts as part of the overall space usage until it has been deleted from the "Trash" box as well. The default for the client is that this occurs automatically at "Logout". (The "Sent" folder is another place to look for extra messages).

Information about managing your e-mail can be found here.
