C# - .NET Or MSSMTP Adding A Line-break In The From Header

I might be just blind (very possible!) but i can't find any information on here/Google anywhere that me out at all :( First up, below is the code i'm using to send the email message:

MailMessage newMM = new MailMessage();
newMM.To.Add(new MailAddress(userEmail));
newMM.From = new MailAddress(getFrom, getFromName);
newMM.IsBodyHtml = true;
newMM.Subject = userSubject;
newMM.Body = userHTML;
if (chkEncoding.Checked)
{
newMM.BodyEncoding = System.Text.Encoding.UTF8;
newMM.SubjectEncoding = System.Text.Encoding.UTF8;
}
NetworkCredential basicAuthenticationInfo = new NetworkCredential(mUsername, mPassword);
SmtpClient smtp = new SmtpClient(mServer);
smtp.DeliveryMethod = SmtpDeliveryMethod.Network;
smtp.UseDefaultCredentials = false;
smtp.Credentials = basicAuthenticationInfo;
smtp.Send(newMM);

Which sends fine, and does UTF8 fine when enabled etc... however in the resulting email i get this (UTF8 or not):

MIME-Version: 1.0
From: "The name i want"
<fromname@fromdomain.com>
To: someone@atadomain.com

And this is from checking the files in MSSMTP Queue folder, so it seems to me its .NET adding the line break in or MSSMTP doing it when it receives the email.
