Spam is generally unsolicited e-mail. It is often commercial, but it can include messages from individuals. We would consider sending unsolicited messages to even a few people to be spam. What you might think is important for everyone to know might not be so to someone else.
School related messages to distribution groups is not considered spam.
What do we do about Spam?
We have a filtering device on our network that blocks spam. In the first two years of its use, it blocked over 2 million messages. That averages out to about 17 messages each day for every user.
