Well, I guess so...  Without seeing examples of what you mean I can't
really comment one way or the other.

If the file is right, then the grep is fine.  If you didn't get mail,
then most likely your sendmail configuration isn't right.

As root, type:

  # mailq -Ac

Does it show you any messages waiting?  If so, your sendmail
configuration is likely the problem.

You're not using any options, and the so that really can't possibly be the
problem.  The grep and wc utilities are ancient Unix work-alikes;
their syntax hasn't changed substantially in about 30 years, barring
the addition or renaming of a few mostly rather esoteric features.  It
really can't; changing the syntax would break 3 decades of code,
probably violate POSIX standards, and definitely irritate a lot of
people.  You're barking up the wrong tree here.
