Why not just install sendmail? :-)

One good reason to use sendmail in this case is that it can do
the address verification for you, if you give it the -bv flag.
It even returns non-zero exit status if you give it bad
addresses.  So you could use it to do most of the dirty word in
any script you cared to write.
