WICHE staff, consultants and constituents that connect to WICHE's network are provided with internet access and e-mail accounts. In the past, email was not monitored or controlled, other than scanning e-mail attachments for viruses with Norton Antivirus for Exchange Server. This has become a problem for several reasons. Just a few of the reasons are viruses, wasted staff time, inappropriate material stored on the network and inappropriate use of network resources. The WICHE Spam filtering solution includes monitoring and restriction of incoming and outgoing email, email attachment and storage limitations and filtering incoming email for Spam. All internal, incoming and outgoing email is scanned on the Exchange server for inappropriate key words. Limits are placed on email accounts, such as mailbox size, message size, attachment size and maximum number of recipients. All incoming e-mail is scanned for several indicators of Spam. These indicators include originating mail server, message subject, sender address, number of recipients and message content, based on key words. The messages are scanned and stopped at a front end SMTP server before they enter WICHE's internal network.
