I am trying to send myself mail from an enquiry form, I am facing an issue that is

When I input my name in the form with a space for example: Rajat Audichya and submit the form I get email naming (unknown sender) and when I just put the first name that is Rajat without the space I get email as Rajat ?

What can I do to overcome this issue?
