|Signature Maker can add blocks of text to the beginning and/or end of all messages originating from a particular user or group of users. Defaults may be setup on a server basis, with overrides available on a per recipient basis. Signatures can be defined with property variables which are then subsituted with the user's specific properties (ie Name, phone, etc). This is ideal for company wide disclaimer statements, or consistent "look and feel" signatures for users, or departments of users.
