Adding line breaks to unformatted emails [RESOLVED]

I’m having the folllowing issue and I’ve tried multiple approaches with no results…

I want to send the form data to an external system. They allow a simple text based email in the following format (just an exaple):

name: Full Name
email: email address
etc...

My current problem is that they don’t allow html and if I turn on the option to turn off auto format it also strips the line breaks (/n) from the notificacion which are needed.

Any ideas how I can add them with a filter or format?

Fixed… I added the code in this article:

Initially I tried it on the Code Snippets plugin but It looks like it was running too late. After moving it to a custom code plugin it worked.
