Message Formatting

I have a simple formatting issue in the {message} field of my notifications emails. For example if the user on my site sends a message using the contact form in the following format :

“Hi,

You have developed a great wordpress contact form plugin but I wish I could…

Learn how to do X or
Learn how to do y or
Learn how to do Z

All the best,
John Smith”

I receive the {message} in the format below :

“Hi, You have developed a great wordpress contact form plugin but I wish I could… Learn how to do X or Learn how to do y or Learn how to do Z All the best John Smith”

How can I format the {message} field to show as the user enters? Thanks in advance.
