Howto automaticall launch Fetchmail on server startup (OSX Server)

I have created a plist file to automatically launch fetchmail on serverstart.
But when trying to run the fetchmail.plist file I get the following error:

./fetchmail.plist: line 1: syntax error near unexpected token `newline'
./fetchmail.plist: line 1: `<?xml version="1.0" encoding="UTF-8"?>'



Her you can find my fetchmail.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN"
 "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
 <dict>
   <key>Label</key>
   <string>fetchmail</string>
   <key>Program</key>
   <string>/etc/mail/Fetchmail_runner</string>
   <key>ProgramArguments</key>
   <array>
     <string>/etc/mail/Fetchmail_runner</string>
   </array>
   <key>RunAtLoad</key>
   <true/>
 </dict>
 </plist>
