Later versions of sendmail use the Sendmail Restricted Shell (smrsh) for
internal shell operations and this doesn't allow redirection, as this
little test shows:

root-# /usr/sbin/smrsh -c 'cat /etc/sendmail.cf > ~/temp.txt'
/usr/sbin/smrsh: cannot use > in command

You should be able to solve this by recompiling your sendmail.cf from the
M4 source without FEATURE(`smrsh').

When I did the same upgrade I ran into problems because relaying is denied
by default. This is clearly a good thing and prompted me to set up proper
restrictions but it's something you might like to keep in mind if you have
more problems.
