/usr/sbin/sendmail.sendmail appears in red 


/etc/alternatives/mta-sendmail appears in red,
designating that it is missing or wrongly configured.

Steve, I also did your suggestions.  Service was not
active and I activated it with your suggestion(s)

service sendmail start

To set it to run automatically enter:

chkconfig sendmail on


Thanks,

Antonio
