Trying to put a new line in an email, not working

I’m trying to send an email that has a body with a “\n” in it, but every time it tries to send it it gives me the error “Error sending email: Invalidy BODY”. I saw another thread where someone said they were putting \n in their email and it worked fine. Any ideas on why it will not work for me? As soon as I take out that \n it will send perfectly. I also tried \r and \cr to no avail. Any help would be appreciated.

Thank you.

/tool e-mail send to="my@email.not" subject="Test" body=".\r\n."

works for me on 3.29, 4.10, 4.11 and 5.0rc9.

Thanks, I tried \r and \n separately, but not together!
