From Funduc Software:
Delivery Agent, one of our Developer Products, is a send-only email program designed for use by web site managers, network administrators, customer relations and support personnel, etc. Delivery Agent was created to allow easy delivery of frequently used, customer-requested email messages (& MIME attachments) such as newsletters, product upgrade announcements, support notes, etc. Messages can be sent to one or more users by selecting a message from a list and entering the users' addresses. The program will also read a text file containing a list of addresses for bulk delivery. Recipients of bulk delivery messages are shielded from seeing the other recipients in the list. Delivery Agent also has a customizable header feature. This can be used to send 'html mail' (see example setting) or specify other special headers.
