ELMHURST,
Do the shipping examples in \examples\internet\ftp_smtp.llb work to sent an e-mail message? This is where I would start. If these examples work fine, then it is something in the code. If they do not work, then I woulg go back through the Internet Toolkit manual and make sure that everything is configured properly.
Another possibility is that the toolkit does not put a blank line between the header and the message body (tat is fixed a future version of the toolkit). Try adding another \r\n at the end of the format string in SMTP Send Message Header.vi and see if that fixes things.
