Right, there is no space between 2 and > allowed. The instructions

You can self test the behaviour with this little commands:
1) cat foo
2) cat foo > /dev/null
3) cat foo 2>&1
3) cat foo 2>&1 > /dev/null
4) cat foo > /dev/null 2>&1
and as a final test run
5) cat foo > /dev/null 2 >&1
So the answer given by Herbert Gasiorowski would be the correct command
setup, if not using a script to check whether an internet connection is
established or if not suppressing mail output from cronjobs by using
MAILTO="".
