If you want to make use of Microsoft's extension library for the Exchange version 5.5 Internet Mail Service from the BackOffice resource kit, but do not want to get involved with configuring the registry and wrapping your text in rich text format codes, then you may find the RedFox IMS Extension Wizard a real help!

The wizard will configure all the registry keys required to enable (or disable) the IMS Extension so that it will append and/or insert text to all inbound and/or outbound messages travelling over the Internet Mail Service.  It will also convert the text messages you enter into the rich text format required by the IMS Extension. 

The wizard will also allow you to optionally restart the Internet Mail Service so that any changes made will take effect immediately.
