Saving an e-mail message in DMS

This I believe would accomplish what you're trying to achieve if you use Outlook or any email program that keeps sent items in a folder.

Send the message. Go into the sent items folder and locate the message. Print the message using the DMS print driver.

If you activate the "save to DMS" icon on your MS Office products toolbar you can click on that icon on your Outlook toolbar and save directly into DMS.
