So why would you want to do this? It helps fighting spam, and you can feed the source into SpamCop to easily report abuse efficiently. Unfortunately, displaying the message source is not particularly simple in IncrediMail, but fortunately it works nevertheless.
View the Source of a Message with IncrediMail
To see the full source of an email in IncrediMail:
- Select the message in IncrediMail.
- Select File | Save As... from the menu.
- Make sure the Mail (*.eml) file type is selected.
- Save the file to a folder (I suggest simply using the Desktop).
- Open the file you just saved in a text editor (Notepad will do fine).
