What is considered spam and what is not?

Tags spam

The definition of spam itself is a tricky issue, and there are many strongly held opinions over what should be included in the definition. Many define spam as unsolicited commercial electronic mail (e-mail) sent in bulk. Others believe 'bulkness' is irrelevant, and the key factor is whether the message sent was asked for or solicited. Still, others debate the importance of whether the message was commercial in nature, and would say that all unsolicited e-mail is spam. This view is perhaps a little extreme, as even messages that are sent to all individuals on campus by IT Services or others as a means of disseminating information could then be viewed as spam.

University of Windsor global spam filter (PureMessage server) analyses all incoming and outgoing Internet mail and applies predefined rules to assign a so called "spam score" to each message. Based on that score the following actions are taken:

All mail that scores between 90%-100% will be deleted from University systems.

All mail that scores between 50% - 90% will be quarantined. Every day at about 3:00 a.m. a digest will be sent to you from the PureMessage Administrator account that informs you of all e-mail that has been received and quarantined within the last 24 hours. If you are using the Notes client or an IMAP client (for example Outlook Express) it will be possible to release the message with one click.

Mail that contains words on the "offensive words" list will be quarantined, even if they score less than 50%. The list that we use comes pre-configured from Sophos with several hundred words and phrases that are generally considered to be unacceptable in e-mail (corporate) communications.

All other mail that scores less than 50% will be delivered to your mailbox.

To secure the campus from e-mail worms and viruses, a number of attachments are not allowed to enter our system. The complete list of attachments is available by clicking here. If there is legitimate mail that you are unable to send because of these restrictions, IT Services suggests that you send the file as a .rtf or .pdf. Alternatively you can .zip the file.
