Title SMTPSEND
Version 2.00
Platform Stated as W95 and NT3.5 or greater.
Description:
SMTPSEND is a simple command line utility to send Internet email from the command prompt or a batch file. It also allows a file to be MIME attached to the email message being sent. It is a Windows 32 console application and will work under Windows NT Version 3.5 or later and Windows 95.

Comments:
I've used it on and off for a few years now, and it appears to work OK on W2K.
I know of a few people who use it for automating sending file attachments in reply to incoming mail and for scheduling a test email to themselves to check the status of a remote mail server.
