1) Follow this: file-uploading-and-attachment
2) Go to your public_html / wp-content / uploads / wpcf7_uploads folder
Here, create a .htaccess file, and add/save this:
# Allow File Attachment From Localhost
order deny,allow
deny from all
allow from 127.0.0.1
After that, try send you a file to your email.
