How to test Multi-part emails using outlook 2007?

I have developed an application in Delphi 7 which will send multi-part emails (both in Text and Html format). Now i want to test it using Outlook 2007.

I have tested each part separately by sending mail as text/plai开发者_如何学Pythonn and text/html. Now i need to test it together using multipart/alternative.

Please advice so that i can test both Text and Html parts.

You can use Thunderbird to test both the parts. There is a provision in this email client to view Plain text and HTML part by changing the view mode of the client.
