How do I send an email from a DOS batch command?

Question

I have a batch file in DOS that does some checking and I need to fire off an email when its done. I've found a few solutions on the interwebz but most of them are 3rd party or just simply open up a new message in Outlook. I need the command to send an email in its entirety without any human interaction.

We use MS Exchange here, if that matters.

Thanks!

Answer 1

Assuming:

1. Your Exchange server accepts emails via SMTP on port 25.
2. You want to send a simple text only email without attachments.
3. It's possible to drive telnet (or a similar telnet client) from a batch file.

You could just send a simple email via Telnet. This link shows an example of how to do it: http://www.yuki-onna.co.uk/email/smtp.html

If assumption 2 or 3 is wrong, you could write a command line SMTP client for sending simples emails fairly easily in many languages and then call it from your batch file.
